We have been studying the charging phenomena on an insulating spacer in vacuum. According to our previous studies, a probe technique for the real-time observation of charging as well as a numerical simulation technique based on Secondary Electron Emission Avalanche (SEEA) mechanism are very useful for understanding the charging phenomena. However, details of the charging process have not been fully understood until now. In the present study, we have conducted current and luminescence measurements in combination with the probe measurement in order to clarify the charging process. A cylindrical insulator made of PMMA (poly-methyl-methacrylate), Al2O3 or Teflon was examined under a ramped voltage excitation. As a result, it has been shown that pulsive currents (mA order in each peak), accompanied by luminescence, flow during the charging. The probe signal (electric field strength at cathode) is an almost linear function of the charge amount obtained by integrating the current pulse. These results show that the current composed of short pulses is responsible for the surface charging in vacuum.
