The present invention provides a technique for constructing compact, high gradient magnetic lenses for charged particle beam focusing. Methods for adjusting the focusing strength of the lenses are provided, based on thermal control, mechanical motion of the magnetic chips within the yoke. The present invention is a method for designing and fabricating permanent magnet focusing elements that are compact, simple to construct, and having a large, adjustable focusing strength. Applications include beamlines for THz radiation sources, free electron lasers, wakefield accelerators and any other charged particle devices that require a compact beamline.
A compact permanent magnet quadrupole lens for charged particle beam focusing comprised of four identical permanent magnetic blocks (PMB) with rectangular or square cross-sections mounted in a supporting structure.
A compact permanent magnet sextupole lens for charged particle beam focusing comprised of six identical permanent magnetic blocks (PMBs) with diamond-shaped or triangular cross-sections mounted in a supporting structure.
A compact permanent magnet multipole lens for charged particle beam focusing comprised of a plurality of multipole beamline magnetic blocks mounted in a supporting structure, wherein the quantity of magnets comprises 2n-poles and the total number of poles is an integer greater than 4.
Use of micro PM quad focusing to efficiently transmit a charged particle beam from a thermionic or photocathode source into an accelerating structure.
