Abstract
This paper gives an overall view of the Superconducting Engineering Test Facility (SETF) at JAERI. SETF is composed of a cryogenic system, a vacuum system, a power supply with protection system, and a data acquisition system. The purposes of SETF are to test not only the Japanese LCT coil, but also high-field, large current toroidal coils or high-energy pulsed coils. The capacity of helium liquefier/refrigerator is 350l/h or 1.2kW at 4.5K. Vacuum tank has 5m diameter and 8m height. The DC power supply and pulsed power supply have the maximum capacity of 30kA-12V, and 3.2kA-300V, respectively. The PDP-11/70 computer system has 680 channels for data processing.
The facility was successfully operated during the cool-down, warm-up, charging, and dumping of the LCT coil. And these tests results demonstrate the high reliability of the facility. Automatic control of the cryogenic system and the leakage of helium gas from the feedthroughs are also described.
