Description
The wide range of operational temperatures of the HTS (YBCO) conductor makes it suitable for the construction of rapid-cycling magnets required for the muon acceleration. The measured ) 0.06 W/m power loss of the 0.4 T magnet operating at 300 T/s suggests realistic possibility of the HTS-based accelerator magnet with much higher B-fields and ramp rates. The magnet core and power cable designs with projected HTS cable power loss for the +/- 1.7 T field in the 30 mm gap at the ramp rate of 1000 T/s are presented. The required supporting cryogenic power and the options of expanding B-field above 1.7 T are discussed.
