Abstract :
This article introduces new space charge measurement systems developed in Japan using the pulsed electroacoustics (PEA) method. The new methods include two types of 3-D systems, two types of transient systems for extremely high or low temperature, a small PEA unit for a portable system, and a mountable PEA unit that can be applied to another facility, such as a vacuum chamber. These new PEA systems should expand the applicable research field.
