RSIC COMPUTER CODE PSR-039
1. NAME AND TITLE
DEM-REFUM-BROAD: Monte Carlo Codes for Calculating Efficiencies and Response
Functions of NaI(Tl) Crystals for Thick Disk Gamma-Ray Sources.
Department of Nuclear Engineering, Kyoto University, Japan.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; FACOM-M 180, FACOM 230/75.
4. NATURE OF PROBLEM SOLVED
DEM-REFUM-BROAD calculates the detection efficiency for a thick disk source on the extended
axis of a 3" dia. x 3" NaI(Tl) crystal, as well as the response function, the photofraction, the total and
peak efficiencies of NaI(Tl) crystals. It can also calculate the response function of Ge(Li) detectors.
5. METHOD OF SOLUTION
DEM-REFUM-BROAD uses analytical and Monte Carlo calculations to obtain the response
functions, total and peak efficiencies and photofractions without Gaussian broadening, both for NaI(Tl)
and Ge(Li) detectors.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for DEM-REFUM-BROAD.
8. COMPUTER HARDWARE REQUIREMENTS
DEM-REFUM-BROAD is operable on the FACOM-M 180 or the FACOM 230/75 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
