Abstract
The power supply design of the /spl gamma//sub t/-jump system in FNAL Main Injector uses a resonant circuit. A critical design parameter is the AC losses of the beam tube in a pulsed quadrupole. This paper gives an analysis to this problem. An equivalent circuit model based on the impedance measurement was established. The measured and calculated losses are in agreement. Another effect of the eddy current is the distortion of the magnetic field inside the beam tube. A Morgan coil was used for field measurements up to 10 KHz. These results are presented in this paper.
