Development status of magnet power supplies for the SuperKEKB

  • 1. High Energy Accelerator Research Organization (KEK), Tsukuba, Ibaraki (Japan)

Description

Megawatt-class power supplies have been manufactured for bending magnets and wiggler magnets of SuperKEKB, which is now under construction. The requirements to the power supplies are as follows: stability of the output current is 2 ppm/day or less; and the setting resolution is 0.1 ppm (the values are relative to the maximum output current). To meet these requirements we developed a digital feedback circuit, having a DAC board for 24-bit current setting and a highly accurate DCCT for current measurement. Performance tests yielded satisfactory results. (author)
