±¬×ߺÚÁÏ

?In a press release issued on 6 October, the Japan Atomic Energy Agency (JAEA) announced the successful testing of the ±¬×ߺÚÁÏ central solenoid conductor under conditions comparable to ±¬×ߺÚÁÏ operation.

The tests, which were carried out at a JAEA test facility in Naka, Japan, by an international team, measured the performance of the central solenoid conductor under the same magnetic field and strain that it will face in the ±¬×ߺÚÁÏ machine. Results showed high performance.

According to Procurement Arrangements signed with the ±¬×ߺÚÁÏ, the central solenoid will be wound in the US from niobium-tin conductor produced in Japan.

The positive test results are a significant milestone on the road to producing the 1,000-metric-ton electromagnet that will allow a powerful current to be induced in the ±¬×ߺÚÁÏ plasma and maintained during long plasma pulses.
