Abstract

A new type of lenses and guides for charged particle beams, especially for relativistic electron beams (REBs) was proposed. When REBs go through small apertures of rings or tubes of high-Tc superconductor, self-induced magnetic fields of the REBs cannot penetrate into the rings and tubes owing to the Meissner effect or the skin effect. The magnetic fields are then compressed and focus the REBs. Copper rings, also, prevent pulsed magnetic fields from penetrating into the rings because of finite time constants for penetration of magnetic field. Copper electrodes have, however, electrical resistivity, and currents induced are reduced in amplitude in these electrodes. Superconductor electrodes are accordingly superior in focusing ability to copper electrodes. These ideas were experimentally confirmed for REBs using electrodes made of Y-Ba-Cu-O compound.
