Magnetic Arrangement for Influencing a Beam of Charged Particles

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is a novel magnet assembly designed to control beams of charged particles, such as those used in particle accelerators. It uses a series of permanent magnets arranged with alternating poles, and for each pole, there are soft-magnetic plates that can be moved in and out of gaps between the magnet surfaces with a motorized mechanism. By adjusting these plates, the magnetic field strength can be efficiently and precisely varied by up to ±20% without substantial changes to the magnet structure or high energy consumption.

Patent Abstract

The invention relates to a magnet assembly for influencing a charged particle beam, the magnet assembly comprising at least 2·n alternately arranged magnetic poles, where n ≥ 2. Here, each magnetic pole is formed at least from one permanent magnet and a yoke with a coil is provided for each pole formed from at least one permanent magnet. The invention is distinguished in that at least one gap, delimited by two permanent magnet surfaces, is formed for each pole and wherein at least one plate composed of a soft-magnetic material and a means for motorized translation of the plate are provided for each pole, so that the at least one plate can be moved into and out of the at least gap one by way of the means for translation. The fields provided by the magnet assembly according to the invention can be varied by up to ± 20 %, based on the operating point.
