Calculation of the Pulse Height Distribution Induced by Fast Neutrons in a Scintillation Detector
The probability distribution of light pulses produced in an organic scintillator by impinging fast neutrons is calculated. It is assumed that the slowing down takes place on a mixture of hydrogen and carbon atoms, and that the light produced is a non-linear function of the energy transferred to the H atoms and a linear function of the transferred energy to C atoms in each individual collision. ...
متن کاملPulse-height loss in the signal readout circuit of compound semiconductor detectors
Compound semiconductor detectors such as CdTe, CdZnTe, HgI2 and TlBr are known to exhibit large variations in their charge collection times. This paper considers the effect of such variations on the measurement of induced charge pulses by using resistive feedback charge-sensitive preamplifiers. It is shown that, due to the finite decaytime constant of the preamplifiers, the capacitive decay dur...
متن کاملdesigning a fast locking pll
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
A Survey on Current Methods of Carpal Height Ratio Measurement and Suggestion of a New Method
Background & Aims: Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram' Methods: This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiogr...
متن کاملA Monte Carlo Code for Simulation of Pulse Pile-up Spectral Distortion in Pulse-height Measurement
The Monte Carlo simulation code CEARPPU has been improved to obtain better accuracy for predicting pulse-height spectra measured at high counting rates. Experimental verification was carried out by measuring an Fe-55 spectrum with a Si(Li) X-ray spectrometer. Based on the spectrum measured at low counting rate, which is considered to be the “true” spectrum with no pulse pile-up distortion, the ...
