Instrumentation of the Central Solenoid Model Coil and the CS insert

The Central Solenoid Model Coil (CSMC) was built by the US and the Japanese home teams as part of an international collaboration which also involved the European Union and Russian Federation. The CSMC and CS insert coil were installed at a purpose build a test facility at the Japan Atomic Energy Research Institute in Naka, Japan and tested from March through August 2000. With over 500 sensors installed on the coils, bus bars, plumbing, facility and the structure, the CSMC and CS insert were instrumented to obtain valuable data about their performances, and to reveal the qualification of the large state superconducting solenoids for the nest fusion machine. This paper describes the instrumentation inside the vacuum chamber used in various stages of the CSMC and the CS insert coil operation.
