内容記述 |
Long pulse beam experiment has been carried out with a multi-aperture and five-stage accelerator with the same gap length, the same aperture interval, and the same aperture diameter as ITER accelerator in order to demonstrate ITER-relevant beam of 230 Am-2 and 870 keV. An actively cooled plasma grid (PG) with compressed air has been newly developed to maintain the PG temperature within suitable range for surface production of hydrogen negative ion (H?) and to realize the stable H? production. It is confirmed that the air-cooled PG has a capability to control the PG temperature within target range for 300 s with feedback control of the air flow rate. The stable beam acceleration with ITER relevant perveance has been successfully achieved for 300 s at 275 keV with PG cooling, 100 s at 500 keV, and 10 s at 750 keV without PG cooling. |
