Radiation tubes and particle accelerators with radiation tubes

Abstract

A radiant tube (4) for guiding a charged particle stream (10) has a hollow cylindrical isolation core (6) directly encompassing a beam-guiding hollow volume (8). The isolation core (6) is formed from a dielectrically acting carrier substrate (14) and an electrical conductor (16) held therein. The conductor (16) is divided into a plurality of conductor loops (20) completely encompassing the circumference of the isolation core (6) at different axial positions of the isolation core (6). The conductor loops (20) are galvanically connected to each other.

Description

technical field [0001] The invention relates to a radiation tube for guiding a charged particle beam and to a particle accelerator with such a radiation tube. Background technique [0002] Such radiation tubes are designed in particular for particle accelerators for charged particles. A charged particle beam may include, for example, electrons, atomic nuclei, ionized atoms, charged molecules, or charged molecular fragments. The charged particle beam is accelerated in a beam-guiding hollow volume enclosed by a radiation tube. The hollow volume is usually evacuated when the particle accelerator is in operation. For this purpose, a vacuum pump system associated with the radiation tube is usually provided. [0003] The radiation tube, which isolates the hollow volume and charged particle beam from the environment, is electrostatically charged by an accelerating electric field. As the field strength of the electric field increases, the probability of scattered electrons escap...

Problems solved by technology

Does not effectively prevent the charging of the metal ring, since the metal ring is embedded in the insulation of the insulating core, and thus the applied charge can only flow out slowly over the creepage distance

Therefore, the operation of the linac with high-speed acceleration pulses leads to an increased probability of breakdown
