The NRL-Isochronous Cyclotron Multi-User On-Line Data Acquisition System

Abstract
The operating features of the SOPHYA (Supervisor of Physics Analysis) system as implemented for an EMR Advance Series 6050 computer at the Naval Research Laboratory's Isochronous Cyclotron are explained. Several independent experiments may be run concurrently with additional capability for a batch processing shadow time job. Each experimenter has acceses to the full library of general routines. The special purpose routines may be coded in Fortran or Assembly Language and included in the library. Standard package includes MATRIX SLICE routines, CRT display routines for single parameter and two parameter contour map or isometric display. Light pen control allows such operations as background subtraction, rotation of axes, etc. A digital method of particle identification is discussed in which an algorithm for evaluation of an identification constant is computed in realtime.
