PEA System

ABSTRACT

This report introduces new space charge measurement systems developed in Japan using pulse-electro acoustic (PEA) method. The methods include 2 types of 3D systems, 2 types of transient systems for extremely high & low temperatures, a small PEA unit for a portable system, & a mountable PEA unit that can be applied to another facility such as vaccum chamber. These new PEA systems expand the applicable research field.
