An integrated facility-wide system for nuclear physics data acquisition is described. Four PDP-11/45‘s connected via a SYSTEM/7 to an IBM/370-168 are used in the system. User programs specifying spectrum definition and analysis logic are written using macros and are expanded into PL11 or PL/1, depending on the subsystem into which the program is to be linked. Both subsystems also use a common command set. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
