Pulse radiation effects in high temperature superconductors

Abstract

Radiation effects in high temperature superconducting (HTSC) films, influenced by pulse electron and ion beams, are considered. The electron beams had kinetic energies E = 200–300 keV, current densities j = 10–2000 Acm2 and pulse duration tp = 0.3–1.2 μs; and ion beams of carbon, copper and silver with E = 200–350 keV, tp = 0.3 μs and j = 5–15 Acm2 were used in the experiments. The results of resistive threshold characteristics measurements by HTSC are described. Questions about the increase of critical current and electric strength of vacuum gaps with electrodes from HTSC are discussed.
