摘要
Superconducting magnet system of steady state superconducting Tokamak (SST-1) shall be operating in a very noisy environment. Presences of high inductive voltages in the magnets during off-normal events like VDE, plasma disruption and PF magnet ramp ups, etc. has made quench detection and data acquisition a challenging task. A hybrid of analog electronic circuits and software-controlled data acquisition system has been developed and tested to safeguard the magnets. This paper will describe the electronic hardware circuits developed for signal conditioning, high voltage suppression, fail-proof quench detection and for noise elimination algorithms and their testing. The SST-1 superconducting magnets will have large number of sensors like voltage taps, Venturi flow meter, strain gages, hall probes, pressure sensors, temperature sensors and displacement transducers. A real time data acquisition system has been designed using VMEbus for monitoring and storing signals from all these sensors and initiating control action in case of off normal events. The paper will also describe the configuration of the data acquisition system with emphasis on hardware used and the software developed for it. (c) 2005 Elsevier B.V. All rights reserved.
