Ageing of CsI thin film photocathodes induced by UV photons
(2007) B.K. Singh; M.A. Nitti; A. Valentini; E. Nappi; C. Coluzza; G. Di Santo; R. Zanoni
The degradation of CsI thin film photocathodes (PCs) under UltraViolet (UV) irradiation has been investigated by measuring the photocurrent as well as the absolute Quantum Efficiency (QE) as a function of the accumulated charge density. Atomic Force Microscopy (AFM) and UV Photoemission Electron Microscopy (PEEM) have been employed to study the surface morphology and the local QE of polycrystalline CsI thin films and their transformation due to UV irradiation. The photoemissive properties of CsI PCs, together with their surface morphology, have been found to be strongly affected by the UV photon ageing. © 2007 Elsevier B.V. All rights reserved.
An apparatus to study the energy and angular distributions of electron-bremsstrahlung photons from gaseous targets
(2014) Namita Yadav; Pragya Bhatt; Raj Singh; B.K. Singh; C.A. Quarles; R. Shanker
An apparatus is developed to measure the energy- and angular distributions of bremsstrahlung generated from collisions of energetic electrons with isolated atoms and molecules. A considerable reduction of thick target bremsstrahlung (TTB) background produced by scattered electrons from the chamber wall is achieved. Details of the experimental setup with regard to design of its components, experimental technique, data acquisition and analysis etc. are given and discussed. The reliability and performance of the setup are demonstrated by obtaining some test results on angular- and energy distributions of bremsstrahlung produced in collisions of 4.0. keV electrons with free argon atoms. These results are compared with the theoretical predictions of the ordinary- and the polarization bremsstrahlung emissions. In this comparison, the experimental data for energy distributions of BS photons are found to be in reasonable agreement while they are found to have noticeable differences in shape of angular distributions. © 2013.
An experimental set up for studying the fusion edge plasma facing materials using TOF mass spectrometry
(Elsevier, 2015) Sunil Kumar; Pragya Bhatt; B.K. Singh; Ajai Kumar; R. Shanker
A new experimental set up is developed to study the fusion edge plasma facing materials under impact of low-energy (40-10,000 eV) atomic and molecular ions. The primary ions are obtained from a low-pressure D.C. gas discharge Colutron ion source. The product ions resulting from the ion-surface interactions involving different processes, for example, surface-induced dissociation (SID), surface-induced reaction (SIR), chemical- and sputtering are detected and identified by using a single-field linear time-of-flight (TOF) mass spectrometer coupled with a time- and position-sensitive dual micro-channel plate detector. The mass spectra of secondary ions are recorded by employing a pulsed extraction and acceleration technique. The experimental set up, experimental technique and data acquisition methodology are presented and discussed. A test experiment is conducted on the developed set up to demonstrate the performance and reliability of the apparatus. For this, a primary beam of 427 eV N2+ ions was chosen to interact with a hydrocarbons covered surface of platinum target kept at room temperature. SID of N2+ into N+ and TOF mass spectra of sputtered, reflected and chemically formed ions from the ion-surface interaction are analyzed. A noticeable feature in the spectra is observed which shows that the odd-electron ions of sputtered hydrocarbons are preferentially produced in the interaction in addition to the other product ions. The nominal mass resolution (M/ΔM) of the present tandem mass spectrometer system is estimated to be about 600, while energy and spatial spreads of the primary ion beam are determined to be about 518 meV and 2.8 ± 0.3 mm respectively. The survival probability of the incident ions is found to be 6.6% suggesting that the major process of ion-surface interaction at the considered impact energy is neutralization. © 2015 Elsevier B.V.

An experimental setup for studying the core-excited atoms and molecules by electron impact using energy analysed electron–ion coincidence technique
(Scientific Publishers, 2017) S. Kumar; S. Prajapati; B. Singh; B.K. Singh; R. Shanker
Operation and performance of an apparatus for studying the decay dynamics relevant to core–hole decay processes in atoms and molecules excited by energetic electrons using an energy analysed electron–ion coincidence technique are described in some detail. The setup consists of a time- and position sensitive double-field linear TOF mass spectrometer coupled with a dual MCP detector and a single-pass CMA to select the energy of detected electrons. Details of different components involved in the setup are presented and discussed. To demonstrate the performance and capability of the apparatus, we present some typical results extracted from the TOF argon ion-mass spectra observed in coincidence with 18-energy selected electrons emitted from interaction of a continuous beam of 3.5 keV electrons with a dilute gaseous target of argon atoms. Specifically, the variation of relative correlation probability for the final ion-charge states Ar1+ to Ar4+ produced in the considered collision reactions as a function of energy of emitted electrons is determined and discussed. © 2017, Indian Association for the Cultivation of Science.
Angular and impact energy dependence of intensity ratio of K α,β x-rays to underneath bremsstrahlung radiation emitted from 15 to 25 keV electrons incident on a pure thick Cu (Z=29) target
(Elsevier Ltd, 2019) Bhupendra Singh; Suman Prajapati; B.K. Singh; R. Shanker
We present new results on angular and impact energy dependence of the relative intensity ratios of K α and K β characteristic (CS) x-ray lines to their respective underneath bremsstrahlung (BS) radiation produced from 15-25 keV electrons incident on a thick polycrystalline pure target of Cu (Z = 29). The angular distributions of relative intensity ratios were carried out by measuring the radiations emitted at incidence angle θ i that varied from 15° to 75° in reflection geometry mode of the target. The x-rays emerging from the target surface were detected by an energy dispersive Si PIN photodiode detector. The magnitude of relative intensity ratio of K α /BS is found to be larger than that of K β /BS by a factor of about 5.11, 5.24 and 5.49 for 15 keV, 20 keV and 25 keV impact energy, respectively measured, for example, at θ i = 15°. However, the intensity ratio of a given characteristic line to its underneath BS increases on average by a factor of about 2.2 in varying the impact energy from 15 keV to 25 keV measured at different angles. The experimental results on angular and impact energy dependence are compared with the corresponding results obtained from Monte-Carlo simulations using the PENELOPE code. The overall agreement between experiment and theory is found to be satisfactory within the uncertainty of measurements. © 2019 Elsevier Ltd
Angular and impact energy dependence of intensity ratio of K x-rays to bremsstrahlung radiation emitted from 10-25 keV electrons incident on a pure thick Cu (Z=29) target
(American Institute of Physics Inc., 2019) Suman Prajapati; Bhupendra Singh; B.K. Singh; X. Llovet; R. Shanker
The variation of relative intensity ratios of the characteristic K x-ray lines, namely, K and K to that of the underneath BS radiation as a function of incidence angle 150-750 under bombardment of 10-25 keV-electrons on a pure thick target of polycrystalline Cu (Z=29) in the reflection geometry mode using a Si PIN photodiode detector has been studied.The comparison of experimental results with those of MC simulations using PENELOPE code shows a good agreement between experiment and theory within the error of measurements for both angular and energy dependence of the considered ratios. The details of these results are presented and discussed in this work. © 2019 American Institute of Physics Inc.. All rights reserved.

Angular dependence of Kβ/Kα intensity ratios of thick Ti and Cu pure elements from 10–25 keV electron bombardment
(Scientific Publishers, 2018) B. Singh; S. Kumar; S. Prajapati; B.K. Singh; X. Llovet; R. Shanker
Measurements yielding the first results on angular dependence of Kβ/Kα X-ray intensity ratios of thick Ti (Z = 22) and Cu (Z = 29) targets induced by 10–25 keV electrons are presented. The measurements were done by rotating the target surface around the electron beam direction in the angular detection range 105° ≤ θ ≤ 165° in the reflection mode using an energy dispersive Si PIN photodiode detector. The measured angular dependence of Kβ/Kα intensity ratios is shown to be almost isotropic for Ti and Cu targets for the range of detection angles, 105° ≤ θ ≤ 150°, while there is a very weak increase beyond 150° for both targets. No dependence of Kβ/Kα intensity ratios on impact energy is observed; while on average, the value of the Kβ/Kα X-ray intensity ratio for Cu is larger by about 8% than that for Ti, which indicates a weak Z-dependence of the target. The experimental results are compared with those obtained from PENELOPE MC calculations and from the Evaluated Atomic Data Library (EADL) ratios. These results on Kβ/Kα X-ray intensity ratios are found to be in reasonable agreement in the detection angle range 105° ≤ θ ≤ 150° to within uncertainties, whereas the simulation and experimental results show a very slight increase in the intensity ratio with θ as the latter attains higher values. The results presented in this work provide a direct check on the accuracy of PENELOPE at oblique incidence angles for which there has been a lack of measurements in the literature until now. © 2018, Indian Association for the Cultivation of Science.

(2006) F.-H. Liu; N.N. Abd Allah; B.K. Singh; T. Ahmad
A multisource ideal gas model is used to give an uniform description of the angular distributions of different kinds of target fragments produced in nucleus-nucleus collisions at high energies. The theoretical results calculated by the Monte Carlo method are qualitatively in agreement with the experimental angular distributions of target black, grey, and heavy fragments produced in 84Kr-Emulsion (Em) collisions at 1.7 AGeV and 16O-Em collisions at 3.7 and 60 AGeV.
Anti-inflammatory properties of BHUx, a polyherbal formulation to prevent atherosclerosis
(2004) Yamini B. Tripathi; M. Mallikarjuna Reddy; R.S. Pandey; J. Subhashini; O.P. Tiwari; B.K. Singh; P. Reddanna
BHUx is a polyherbal formulation consisting of water-soluble fractions of five medicinal plants (Commiphora mukul, Terminalia arjuna, Boswellia serrata, Semecarpus anacardium and Strychnos nux vomica). The present study was undertaken to evaluate its antioxidant and antiinflammatory effects. BHUx, standardized by HPLC fingerprinting and filtered through 0.2 μm filter paper, was employed for different studies under in vivo and in vitro conditions. Under in vivo conditions, BHUx significantly reduced inflammation in the carrageenan-induced rat paw oedema model of inflammation, suggesting its anti-inflammatory properties. In order to test the mechanism of action of BHUx, further in vitro studies were undertaken on cumene-hydroperoxide-induced lipid peroxidation (CHP) in liver homogenate, LPS-induced NO production in peritoneal macrophages and on key enzymes of arachidonic acid cascade, involved in the mediation of inflammation. Under the conditions, BHUx showed concentration-dependent inhibition of CHP-induced lipid peroxidation in liver homogenate, suggesting its antioxidant properties. Similarly the potent anti-inflammatory effects of BHUx are evident by (a) preferential inhibition of COX-2 (IC50 for COX-2 = 80 μg/ml and IC50 for COX-1 = 169 μg/ml), (b) low ratios in the IC50 values of COX-2/COX-1 (0.47), (c) decreased production of NO in LPS-induced peritoneal macrophages and (d) inhibition of 5-LOX (IC50 = 795 μg/ml). BHUx also showed a preference for inhibiting 15-lipoxygenase (IC50 = 44 μg/ml), a key enzyme implicated in LDL oxidation. These studies suggest that BHUx is acting mainly at three levels, i.e., as a potent natural antioxidant, by reduction of key inflammatory mediators of arachidonic acid cascade and by preventing 15-LOX-mediated LDL oxidations, to prevent atherosclerosis.

The azimuthal anisotropy coefficients v2 and v4 of π0 and η mesons are measured in Au + Au collisions at sNN=200 GeV as a function of transverse momentum pT (1-14 GeV/c) and centrality. The extracted v2 coefficients are found to be consistent between the two meson species over the measured pT range. The ratio of v4/v22 for π0 mesons is found to be independent of pT for 1-9 GeV/c, implying a lack of sensitivity of the ratio to the change of underlying physics with pT. Furthermore, the ratio of v4/v22 is systematically larger in central collisions, which may reflect the combined effects of fluctuations in the initial collision geometry and finite viscosity in the evolving medium. © 2013 American Physical Society.

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations where one particle is an electron from the decay of a heavy-flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interactions between heavy quarks and the matter, such as whether the modification of the away-side-jet shape seen in hadron-hadron correlations is present when the trigger particle is from heavy-meson decay and whether the overall level of away-side-jet suppression is consistent. We statistically subtract correlations of electrons arising from background sources from the inclusive electron-hadron correlations and obtain two-particle azimuthal correlations at √sNN=200 GeV between electrons from heavy-flavor decay with charged hadrons in p+p and also first results in Au+Au collisions. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to p+p collisions. © 2011 American Physical Society.

Charged-pion-interferometry measurements were made with respect to the second- and third-order event plane for Au + Au collisions at √sNN200 GeV. A strong azimuthal-angle dependence of the extracted Gaussian-source radii was observed with respect to both the second- and third-order event planes. The results for the second-order dependence indicate that the initial eccentricity is reduced during the medium evolution, which is consistent with previous results. In contrast, the results for the third-order dependence indicate that the initial triangular shape is significantly reduced and potentially reversed by the end of the medium evolution, and that the third-order oscillations are largely dominated by the dynamical effects from triangular flow. © 2014 American Physical Society

The PHENIX collaboration presents first measurements of low-momentum (0.41 GeV/c) direct-photon yield dNγdir/dη is a smooth function of dNch/dη and can be well described as proportional to (dNch/dη)α with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high pT (>5 GeV/c), but when results from different collision energies are compared, an additional sNN-dependent multiplicative factor is needed to describe the integrated-direct-photon yield. © 2019 authors.

The present experiment was conducted at the Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, BHU, Varanasi during the Rabi season of 2016-17 to evaluate the efficacy of fungicides against Cercospora leaf spot and powdery mildew diseases of chilli cv. Punjab Guchhedar. A variant with no application of fungicides was used as a control. All fungicidal treatments reduced the disease severity as compared to the untreated control with a corresponding increase in yield. Application of Tebuconazole 430 SC (500 ml/ha) significantly reduced the diseases and ultimately recorded the highest yield (139.00 q/ha) followed by Tebuconazole 430 SC (440 ml/ha) with yield 137.39 q/ha. The overall results revealed that Tebuconazole 430 SC at both the concentrations (500 and 440 ml/ha) effectively reduced the disease severity and increased the yield as compared to untreated control.
