However, regarding most studies related to the surface charging, their measurements were carried out after high voltage excitation or flashoverevents. In this research, the measurement of 2-dimensional surface charge distributions in real time has been carried out in vacuum by Pockels effect. With this measuring method, the charge distributions on a dielectric sample can be measured from the high voltage application to the surface flashover event. This paper describes the changes of the surface charge distributions on a PET film under non-uniform ac voltage application in vacuum. Moreover, using this method, the charge distribution before and after one flashover event on the PET film has been measured., text, application/pdf}, pages = {6--13}, title = {超伝導量子干渉素子アレイを用いた低雑音増幅器に関する研究<論文>}, volume = {38}, year = {2005}, yomi = {モロオカ, トシミツ and ミョウレン, ヒロアキ and タカダ, ススム} }
