	The purpose of this paper is to estimate the conducted and radiated Electromagnetic Interference (EMI) for subsystems in the TPS booster ring. A LISN (Line Impedance Stabilizing Network) system with a wide frequency range was conducted to measure the EMI spectrum of pulsed magnet system. The radiated EMI was tested by magnetic field probe, which the measurement frequency range is 100 kHz ~ 3 GHz. A stray current was tested by wide frequency current transformer in order to measure the conducted current for kicker and septum systems. According to the experiment results, the stray current could flow through the other subsystems or booster chamber, and it might be affected the stability of booster operation. Therefore reducing and eliminating the interference of EM waves will be a very important issue. The EMI prevention scheme will be continued.

A LISN (Line Impedance Stabilizing Network) system with a wide frequency range was conducted to measure the EMI spectrum of pulsed magnet system. The radiated EMI was tested by magnetic field probe, which the measurement frequency range is 100 kHz ~ 3 GHz. A stray current was tested by wide frequency current transformer in order to measure the conducted current for kicker and septum systems. According to the experiment results, the stray current could flow through the other subsystems or booster chamber, and it might be affected the stability of booster operation. Therefore reducing and eliminating the interference of EM waves will be a very important issue. The EMI prevention scheme will be continued.
