4.2.4. Corrections for Measurements with Proton Recoil<br />

Counters<br />

The programs WALLEND, FITPRO, and SERECO (Aldermaston)<br />

have "been modified and partly corrected. WALLEND has<br />

been used on the IBM 7090 (360) for the calculation<br />

of the influence of wall- and end corrections for cylindrical<br />

counters on the measurement of proton recoil<br />

spectra.<br />

With program FITPRO background and dead-time corrections<br />

of the experimental proton recoil spectra and comparisons<br />

between the corrected spectrum and the theoretical<br />

one obtained from WALLEND have been performed.<br />

SERECO has been used for the calculation of geometrical<br />

corrections and energy degradation of recoil protons.<br />

An IBM 7090 (360) program in FORTRAN IV for the calculation<br />

of complicated integrals for the flux of recoil<br />

protons has been written. The program is being tested.<br />

4.2.5. Total Cross Section <strong>Data</strong> Reduction in the High Energy<br />

Range<br />

A PORTRAIT program for data plotting, dead-time corrections,<br />

calculations of transmissions and total cross<br />

sections has been written and used to process carbon<br />

data.<br />

4.3. System Analysis and Programming<br />

H. Horstmann, H. Schmid<br />

4.3.1. Programming of the IBM 1800<br />

A system of on-line and off-line data analysis programs<br />

for the IBM 1800 is being written and tested.<br />

This system includes interrupt routines for digital<br />

data input, on-line data reduction and display functions,<br />

off-line calculations, a complete set of plotter routines,<br />

teleprocessing programs, and many general utility<br />

routines.
