Development of J-PARC MR Main Magnets Power Supplies for High Repetition Rate Operation
Abstract
The Japan Proton Accelerator Research Complex (J-PARC) aims at achieving a megawatt-class proton accelerator facility. One of the promising solutions for increasing the beam power is to increase the repetition rate of the Main Ring (MR) from the current rating of 0.4 to 1.0 Hz. However, in this scheme, the increase in the output voltage and the power variation in the electrical power supply are serious concerns for the main magnets. At the same time, a current-ripple reduction is required to increase the beam quality. This paper introduces the power supply (PS) system of the J-PARC MR main magnets which has the potential to overcome these issues, and reports the design and test results of the prototype PS developed.
