    Notes: Diagnostic data acquisition on Princeton's tokamak fusion test reactor (TFTR) is accomplished via CAMAC (computer automated measurement and control system). This paper describes the capabilities of this instrumentation technique as applied to TFTR diagnostics and presents the family of CAMAC modules and equipment necessary for TFTR data acquisition and process control. These modules provide system configurations that range from meeting the basic requirements of digital and analog input/output to the requirements of transient digitizers, scalars, histogramming memory controller (each with add-on memory storage), timing and sequencing and timed gate units, function generators, and microprocessor interface units. The applications and guidelines that have evolved from our experience with TFTR CAMAC are presented.

    Neutral pressure and gas flow instrumentation for TFTR (1985)

    Notes: The design and operation of instrumentation included in the gas injection system of the Tokamak Fusion Test Reactor (TFTR) for torus pressure and gas flow measurements are described. Magnetically shielded ion gauges, located on the torus boundary, are used for fast (1 kHz) torus pressure measurements over the range 10−7–10−3 Torr. Gas injection assemblies comprising an array of piezoelectric gas injection valves are situated at three toroidal locations. The gas injection valves are programmed for various discharge conditions including feedback control from the torus pressure gauges and plasma density measurement. Gas flow through the injection valves is monitored by strain-gauge-type pressure transducers on each injection valve. The resulting gas flow measurements are used for gas fueling, particle balance, and recycling studies.
