Computer Network - based data acquisition and control system for the imaging element of the TACTIC array

Abstract

An interrupt-driven distributed Data AcQuisition and Control System (DAQCS) has been developed for the Imaging Element of the 4-element gamma-ray telescope array, TACTIC. A network of PCs, running the QNX RTOS, have been coupled to the front-end CAMAC-based instrumentation modules. Single-point monitoring and control from a designated node with an elaborate GUI has greatly facilitated the operation of the telescope and its sophisticated, multi-pixel imaging camera.
