The PF Insert Coil test facility in Naka, Japan. The test coil has recently been installed in the chamber (centre).
The Poloidal Field Insert Coil test in the CSMC facility at Naka, Japan, is currently underway, with the coils now at 75K in the cooldown stage. The NbTi PF insert tests a 40m length of the PF6 conductor in a 6T background field provided by the CSMC, simulating the operating conditions of the PF6 coil. The superconducting test is expected to start in late June and will be completed by August.
