1. NAME AND TITLE
CALOR95: Monte Carlo Code System for Design and Analysis of Calorimeter Systems, Spallation Neutron Source (SNS) Target Systems, etc.
AUXILIARY CODES
HETC, MORSE, EGS4
2. CONTRIBUTOR
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran 77, IBM RS/6000 and SUN (C00610/MNYWS/00).
4. NATURE OF PROBLEM SOLVED
CALOR95 is a Monte Carlo code system, written in Fortran 77 that is designed to assist experimentalists in evaluating and analyzing different types of calorimeter systems used in many high-energy physics experiments to determine the energy and direction of incident hadrons, leptons, and photons. This code package contains HETC95, SPECT95, EGS4, MORSE, and other support programs. PSR-261/MICAP, also available from RSICC for IBM mainframe, can be modified for workstation and substituted for MORSE. In April 1996 CALOR95 replaced CALOR89 in the RSIC code collection. In July 1998 the MORSE code was replaced when it was found that previous versions of MORSE in this system did not yield the correct energy balance because absorbed gamma-ray energies were underestimated. No other modules were changed.
5. METHOD OF SOLUTION
HETC95 transports p, n, Pi+, Mu+ in the energy range from the source-particle energy down to a specified energy cutoff using the MONTE CARLO methods to solve the Boltzman transport equation. SPECT calculates the energy depositions or "effective energy deposition" associated with the hadronic particles. EGS4 transports the gamma-rays from Pio decay and the e+ from Mu+ decay. MORSE transport the low energy neutrons (<20 MeV), and gamma rays produced during this phase are stored and transported using EGS4 or can be transported by MORSE.
6. RESTRICTIONS OR LIMITATIONS
None noted.
7. TYPICAL RUNNING TIME
Depends on the number of histories and energy of the source particles. Times notes for the sample problems on an IBM RISC 6000 Model 590.
HENMT88 2 seconds XSMORSE 9 seconds
HETC 4 seconds MORSE 17 seconds
EGSPREP 1 second LIGHT 7 seconds
PEGS 23 seconds SPECS 1 second
EGS4 30 seconds
8. COMPUTER HARDWARE REQUIREMENTS
The system runs on IBM RISC 6000 or SUN workstations with a minimum of 4 Mbytes of memory and 100 Mbytes of disk storage.
9. COMPUTER SOFTWARE REQUIREMENTS
CALOR95 was tested on an IBM RISC 6000 Model 590, under the AIX 3.2.5 operating system, using the IBM XL FORTRAN Compiler Version 3.2.2.3. It was also tested on Sun OS/5.6 using the Fortran 77 4.2 compiler. Note that the CERN library routines included in this package are in an archive library and are system dependent.
