Instrumentation of the Central Solenoid Model Coil and the CS insert

The Central solenoid Model Coil (CSMC) was built by the US rind the Japanes e 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 test facility at the Japan Atomic Energy Rese arch Institute in Naka, Japan and tested from March through August 2000, Wi th over 500 sensors installed on the coils, bus bars, plumbing, facility an d the structure, the CSMC and CS insert,were instrumented to obtain valuabl e data about their performances, and to reveal the qualification of the lar ge scale superconducting solenoids for the next fusion machine. This paper describes the instrumentation inside the vacuum chamber used in various sta ges of the CSMC anti the CS Insert coil operation.
