| 摘 要： | CSR power supply system made a great progress in 2003. All power supplies for CSRm E-cooler have been accepted and put into operation since Feb. 2003. And we are preparing to test power supplies of CSRe cooler 31 sets pulsed convertor for CSRm quadruple magnet arrived in IMP. But their output current must be increased from 590 A to 700 A, because of higher beam energy. 12 of them can fit the new request, but the others have to be redesigned and reproduced. The dipole power supply was assembled in plant and by using the power supply was some experiment made. The first test results was excited. Now this device has been installed in IMP and connected with the dipole magnet. We invited a public bidding for RIBLL2 and CSRe power supplies last September. Two companies provided 128 power supplies, which will be delivered to IMP before June 2004.
