General Atomics (GA) is under contract to UT-Battelle c/o Oak Ridge National Laboratory for the fabrication of ITER Central Solenoid Modules (CSM). GA will provide seven modules to ITER Organization (IO), six of which will be assembled in a stack that forms the ITER Central Solenoid. All CSMs are required to pass factory acceptance testing (FAT) at General Atomics’ Magnet Technology Center (MTC) test facility prior to shipment to IO. Currently, CSMs 1, 2, and 4 have completed FAT and have been delivered to IO. CSM5 has completed FAT and CSM3 will repeat FAT after resuming its test campaign. FATs on CSMs 6 and 7 are planned as the modules complete fabrication. The MTC test facility was designed and built to conduct CSM factory acceptance tests. The test facility consists of the test chamber, high vacuum system, 4.5 K recirculating supercritical helium refrigeration plant, 50 kA DC power supply, capacitor-pulsed DC circuit breakers, 1 GJ discharge resistor, high-temperature superconducting current feeders, data acquisition system, supervisory control and magnet quench protection system, and a multitude of supporting equipment. Where possible, the test facility utilizes similar equipment planned for use at IO for magnet operation. The test facility operational lessons learned as a result of CSM 1–4 FATs are presented and discussed in this paper.
