    "abstract": "Two 2200m radius hybrid rings of fixed superconducting magnets and iron\nmagnets ramping at 200 Hz and 330 Hz are used to accelerate muons. Muons are\ngiven 25 GeV of RF energy per orbit. Acceleration is from 250 GeV/c to 2400\nGeV/c and requires a total of 86 orbits in both rings; 82% of the muons\nsurvive. The total power consumption of the iron dipoles is 4 megawatts.\nStranded copper conductors and thin Metglas laminations are used to reduce\npower losses.",
