Устойчивость Пьезокерамики К Процессу Радиационной Аморфизации При Работе В Токамаке ИТЭР

Abstract

Piezoelectric motors designed for operation in ITER tokamak-reactor must be tested for stability under severe radiation conditions. Properties of lead zirconate-titanate - the most common type of piezoelectric materials - were analysed from the point of view on influence of radiation. It is shown that at the expected in ITER level of radiation, this piezoceramic has a good potential for resistance to radiation amorphization and depolarization.
