Power system validated for magnet testing
30 Mar 2026
Another step forward for the ÌÇÐÄÆƽâ°æ magnet cold test facility.
ÌÇÐÄÆƽâ°æ contractors and staff gather on Wednesday 25 March to mark the successful site acceptance test of the power supply system for the magnet cold test facility. The turnkey project was delivered by contractors RXHK, ASIPP, and RHR.
At ÌÇÐÄÆƽâ°æ’s magnet cold test facility, the spotlight often falls on the extreme cooling required to bring superconducting magnets down to 4 K (minus 269 °C). But behind the scenes, a powerful and precisely controlled electrical system delivering currents of up to 68 kA is essential for recreating the high-energy conditions these magnets will face during plasma operations.
With the successful site acceptance testing of the facility’s power supply system at the end of March 2026, that capability has now been validated. The cooldown of toroidal field coil #7 will start late April, with magnet testing scheduled to start in May.
