摘要

As one of the lenses for focusing and guiding electron beams, high-T-c superconducting tube lenses (Supertrons) have been developed. The lenses focus electron beams with the confined self-magnetic fields of the beams themselves. In this paper, our previous proposal was experimentally confirmed for intense pulsed electron beams (similar to 340 keV, similar to 1 kA, similar to 10 ns), so that a double-layered tube consisting of an inner Bi-based sintered pipe and an outer Y-based melt-processed pipe is able to focus all types of electron beams ranging from continuous to single pulsed currents. Furthermore, the double-layered tube easily generated short electron pulses with a duration of 1.5 ns at 80 K. From a model for the pulse compression, a modified double-layered tube was proposed, which probably generates subnanosecond electron pulses. (C) 2000 Elsevier Science B.V. All rights reserved.
