Steering Magnet Power Supply Control System for the TRISTAN AR

The closed orbit distortion of TRISTAN Accumulation Ring (AR) is corrected by the steering magnets1-2 (correction dipole magnets). These magnets are excited by the bipolar power supplies with the rated power of about 1 KVA. The power supplies are controlled remotely through the serial camac dataway3. The camac modules which include the microprocessor are developed for this system and these modules send out the reference current patterns to the individual power supply.
