Radiation effects in polycarbonate capacitors

Abstract

The aim of this paper is to examine the influence of neutron and gamma irradiation on the dissipation factor and capacitance of capacitors with polycarbonate dielectrics. The operation of capacitors subject to extreme conditions, such as the presence of ionizing radiation fields, is of special concern in military industry and space technology. Results obtained show that the exposure to a mixed neutron and gamma radiation field causes a decrease of capacitance, while the loss tangent remains unchanged.Cilj ovog rada je da ispita uticaj neutronskog i gama zracenja na faktor gubitaka i kapacitivnost kondenzatora sa polikarbonatnim dielektricima. Rad kondenzatora izlozenih ekstremnim uslovima, kao sto je prisustvo jonizujuceg zracenja, od posebnog je znacaja za vojnu industriju i tehnologiju svemirskih letelica. Dobijeni rezultati pokazuju da izlaganje kombinovanom polju neutrona i gama zraka dovodi do smanjenja kapacitivnosti polikarbonatnih kondenzatora, dok tangens ugla gubitaka ostaje nepromenjen.
