CHERS software system: A microVAX-based diagnostic
The charge exchange recombination spectroscopy (CHERS) diagnostic is the first tokamak fusion test reactor (TFTR) diagnostic to utilize a microVAX II computer for device control, data acquisition, analysis, and event-driven processing. The CHERS system is controlled from a single interactive menu-driven process, enabling the diagnostic physicist to perform interactive device control and monitoring, calibration and control file editing, and to control automatic device setup, data acquisition and display, and postshot analysis. All software is written in f-smcapso-smcapsr-smcapst-smcapsr-smcapsa-smcapsn-smcaps. Device control is accomplished using the (ORNL) VAX CAMAC and TAU real-time image processing system (RTIPS) f-smcapso-smcapsr-smcapst-smcapsr-smcapsa-smcapsn-smcaps subroutines. Standard VAX system services are utilized, including the use of event flags, global sections, logical names, security services, process control, and spawning of subprocesses.
