Description
Commissioning of Japan Proton Accelerator Research Complex (J-PARC) main ring (MR) was started on May 2008. Very large magnetic field ripples of the order of 10-2 were found in the dipole, the quadrupole and the sextupole magnets in the MR. In order to reduce the ripples, we modified the magnet-power supplies, which includes removal of the 600Hz trap filter. Due to the removal of the trap filter, major components of current ripple frequency is 600Hz and the higher orders. We have to re-install the 600Hz trap filters on the magnet-power supplies. Thus analysis of the control circuit has done at first. (author)
