A 650 mm long liquid hydrogen target for use in a high intensity electron beam
Abstract
A 650 mm long liquid hydrogen target constructed for use in the high intensity electron beam of the linear accelerator is described. The main design problem was to construct a target that would permit the heat deposited by the electron beam to be removed rapidly without boiling the hydrogen so as to maintain constant target density for optimum data taking. Design requirements, construction details and operating experience are discussed. A hydrogen target system that could absorb up to 250 watts of beam power with flow parallel to the beam direction was produced. Liquid mixing transverse to the beam direction limited the local boiling in the beam spot to 7%.
