Abstract:
A compact, high radio-frequency driven, plane wave transformer photoelectron linear accelerator having a longitudinal axis for producing a polarized bunched electrons having low emittance comprising:a plurality of cylindrical disks positioned inside a cylindrical tube, which is capped at either end with an end plate, said tube having an inner wall coated with a getter material; means for applying high-frequency rf electric field along the longitudinal axis of the said disks, said electron bunches being rapidly accelerated by said electric field; a photocathode having a surface with a thin layer of semiconductor material deposited thereon; said photocathode being illuminated by a circularly polarized laser beam thereby emitting polarized electrons; means for producing a high vacuum necessary to protect said photocathode activated surface; and a magnet focusing system positioned in operative relationship to said accelerator for focusing the bunched electrons.
