STANDARD SAMPLE FOR MEASURING SPACE CHARGE, AND METHOD OF MEASURING SPACE CHARGE

摘要

PROBLEM TO BE SOLVED: To provide a standard sample capable of regularly providing stable distribution of space charge and accumulated quantity of space charge by providing electrodes formed of a pair of conductors opposite to a body formed of a ceramic sintered body. ;SOLUTION: Circular thin plate-like electrode parts 3, 3 formed of a pair of conductors are provided on both surfaces of a body 2 formed of ceramic sintered body which constitutes a standard sample 1 so as to be opposed thereto. As the material forming the body 2, a ceramic sintered body dielectric body generally used as ceramic capacitor which is a dielectric body having the performance of almost scattering the space charges accumulated in the body 2 by voltage application by grounding is preferred. For example, a sintered body of titanium oxide is used. As the conductors forming the electrodes 3, 3, aluminum, gold and the like are used. The diameter of the standard sample 1 is set to 100-120mm, and the thickness (t) of the standard sample 1 (body 2) corresponding to the space between the electrode parts 3, 3 is set to 1-3mm. The electrode parts 3, 3 have diameters of 20-40mm and thicknesses (a), (a) of 1.0-3.0mm.;COPYRIGHT: (C)1997,JPO
