Manuscript Title: EFYGA: a Monte Carlo program to compute the interaction probability
and the counting efficiency of gamma rays in liquid scintillators. | ||

Authors: E. Garcia-Torano, A. Grau Malonda | ||

Program title: EFYGA | ||

Catalogue identifier: ABBC_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 47(1987)341 | ||

Programming language: Fortran. | ||

Computer: VAX 11/785. | ||

Operating system: VAX/VMS. | ||

RAM: 15K words | ||

Word size: 32 | ||

Keywords: Nuclear physics, Activity detection, Photon transport, Monte carlo codes, Liquid scintillation, Efficiency. | ||

Classification: 17.6. | ||

Nature of problem:This program computes the interaction probability and the counting efficiency of gamma photons in toluene scintillators for a given energy. | ||

Solution method:The Compton-electron distribution produced by the gamma ray-scintillator interaction is simulated by means of a Montecarlo process. The counting efficiency is then computed by computing the efficiency for every point in the distribution and summing up to obtain the total efficiency. | ||

Restrictions:None. | ||

Running time:The test requires about 10 m of CPU time for a VAX 11/785 computer with the machine-independent random numbers generator. If the FORTRAN 'RAN' function is used in a VAX, the time is about 3 minutes. |
