The large-scale and engineering preparation of NiPd powder with an excellent structure is crucial for promoting the development catalytic applications utilization hydrogen energy. In this study, micro-nano dual-size alloy a flake-like microstructure was synthesized using simple efficient high-energy ball milling method. Micro-structural analysis performed on samples at various stages to investigate atomic migration refinement mechanisms during process. elemental distribution different...
To overcome the temperature effect of NaI(Tl) detectors for energy spectrometry without additional hardware, a new correction method was put forward based on pulse deconvolution, trapezoidal shaping and amplitude correction, named DTSAC. verify this method, actual pulses from NaI(Tl)-PMT detector were measured at different temperatures -20℃ to 50℃. Pulse processing spectrum synthesis showed that position drift 662 keV peak less than 3 keV, corresponding resolution sum spectra ranges 6.9%...
Abstract Energy‐dispersive x‐ray fluorescence spectra often suffer from background caused by primary x‐ray. Therefore, correction is of great significance that must be performed before subsequent analysis. In this article, a subtraction method based on morphological operation was proposed. The and the smoothing factor could effectively reduce possibility underestimation, especially for noisy spectrum. verified simulated experimental data, comparisons with other peak‐clipping penalized least...

We used the Monte Carlo simulation method to establish a detector response matrix and non-negative least-squares deconvolute x-ray spectra. The experimental data verified effectiveness of this method, influence full-width at half maximum calibration accuracy on deconvolution results was investigated. had high efficiency compared with others. showed that, except for Zn, relative errors between inversion standard values were less than 0.1% simulated For data, within 0.2%. peaks similar...
Abstract Shashlik tower, which is composed of absorbers and scintillators alternately, surrounded by reflector coupled with Silicon Photomultiplier (SiPM) Wavelength-Shifting (WLS) fibers, a significant component to measure the energy position photons electrons in Electromagnetic Calorimeter (ECal), key detector Multi Purpose Detector (MPD) at Nuclotron-based Ion Collider facility (NICA) Russia. In this paper, effect materials adopted for absorber, WLS fiber, length curvature fibers incident...
Two batches of diodes, with different structural ratios (the ratio area and thickness), were made using manufacturing processes. The energy response the first batch to 15 kinds monoenergetic neutrons ranging from 180 keV 17.56 MeV was tested, neutron source both 239Pu–Be measured. deposition in diodes irradiated by 1 20 calculated simulation procedure. curve experimental results showed an approximately similar trend that theoretical computation. Based on experiments, it concluded fast varied...
