| Abstract |
The performance of the power supply for the dipole magnet is important for the TPS booster ring. The output current of the power supply follows the beam current from 150 MeV ramping to 3 GeV. The frequency of the power supply is 3 Hz. The power supply must thus push enormous energy into the dipole magnets at +1000 V and +1000 A, and can handle this job. Because the TPS booster dipole supply is bipolar and the voltage is large, the lodged capacitors have large effects that produce common-mode high-frequency current noise, which drives the power supply beyond specification. The TPS booster ring hence fails to meet the dc and ramping specification. We designed a common-mode filter to solve the high-frequency current noise by absorbing the current noise from the path of the lodged capacitors to the ground pad. The TPS booster dipole supply thus works within the specification when the power supply is in the dc or ramping mode. The beam current from the 150- MeV dc mode for the injection mode can ramp the beam current to 3 GeV. This paper reports the excellent results.
