Study on surface charge distribution of an insulating hollow cylinder in vacuum

This paper deals with the surface charge on the inner surface of an insulating hollow cylinder. We measured the charge by employing an electrostatic probe before and after the spark conditioning procedure. The probe output after the conditioning showed much uniform pattern with respect to the circumferential direction. The computer simulation was also conducted to analyze the charge distribution. The simulation results showed that the probe output was sensitive to the density of electric flux on the outer surface resulting from the SEEA charge.
