Design and test of HTS magnet for circular planar magnetron cathode

摘要

Highlights?One 3 inch circular planar magnetron cathode excited by HTS magnet is designed, fabricated and tested.?The design optimization of the magnet is performed with two optimization objectives.?The cathode could generate the magnetic field larger than 0.13 T on the target surface.AbstractThe HTS magnet with half-closure iron yoke is investigated for circular planar magnetron cathode application. The design optimization of the magnet is performed with two optimization objectives: the maximum value of the horizontal component of magnetic field (Br) on the target surfaceBr1max, and the maximum value ofBrwhere the magnetic field is parallel to the target surfaceBr2max. Aimed at the magnetron cathode with 3 inch target, the HTS coils are fabricated with YBCO tapes, an
