The charge distribution on an insulating sheet induced by a surface discharge can be directly observed by "Dust figure". "Discharge chamber" is a sensitive high energy particle detector with a luminous trajectory. The high frequency breakdown voltage as a function of pl and fl is an extension of Paschen's law in de discharge. The recombination loss predominant to attachment one was found in an afterglow of water vapour with the high electron density of plasmas by the phase angle of the reflection coefficient of a wave. The ripple of the electron temperature of high frequency produced plasma was measured as function of frequency for various pressures. An improvement of a laser interferometer to eliminate the fluctuation of the detected signal induced by the mechanical vibration of the system is developed.
