MCBETH: liquid scintillation counting spectra computation at the dynodic output of the photomultipliers

Abstract
This paper presents a Monte Carlo based FORTRAN code to generate the final electron pulse height spectrum obtained at the anode of a liquid scintillation counting system. The code simulates the detection of beta particles in a toluene scintillator, the generation of photoelectrons, the subsequent electron amplification by a single photomultiplier tube or by two photomultipliers working in summed-coincidence mode, the final anode output pulse, and eventually the pulse-height histogram. ...

Title of program: MCBETH
Catalogue Id: ADCI_v1_0

Nature of problem
The detection of beta emitters by liquid scintillation counting (LSC) involves a number of processes, namely, energy deposited, light production, light atenuation, photoelectron generation and signal amplification in a photomultiplier tube (PMT). Besides, a good knowledge of the spectral response of LSC systems is important to characterize accurately some related problems, like wall effect, complex beta-spectra deconvolution, ionization quenching effect, in order to obtain a possible absolute st ...
