RSIC COMPUTER CODE PSR-056

1. NAME AND TITLE

GAINCALB: Determination of the Gain Used with Organic Scintillation Detectors.

2. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

Fortran IV and Assembler Language; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

GAINCALB determines the gain (in terms of light units) employed in neutron spectroscopy experiments using organic scintillation detectors.

5. METHOD OF SOLUTION

GAINCALB is designed to take a calculated distribution of the energy deposited by Compton electrons from the 1.274-MeV ²²Na gamma ray in the NE-213 detector under consideration, convert this distribution into one resembling an experimental pulse-height distribution by smearing the former with a Gaussian, and matching the resulting function to the experimentally determined pulse-height distribution, using a least-squares fitting procedure.

6. RESTRICTIONS OR LIMITATIONS

Among input required is a theoretically determined distribution of the energy loss from Compton electrons in the scintillator; however, the calculation of such a distribution is not part of the GAINCALB package.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running times for GAINCALB.

8. COMPUTER HARDWARE REQUIREMENTS

GAINCALB is operable on the IBM 360/370 computers.

9. COMPUTER SOFTWARE REQUIREMENTS

Fortran IV and Assembler Language compilers are required.
