Abstract:

The preliminary development of a high intensity molecular beam, in which a small tailoredinterface hypersonic shock-tunnel is used as the gas source, is reported. The aim is to extend molecular beam techniques into the 1-10 e.v. per particle range by utilizing the capability of the shock tube to generate high temperatures. A 0.7 e.v. nitrogen beam was produced in the pilotAPPARATUS. The intensity of 2.5 x 10 to the 18th power molecules 1sq.cm.sec. and the spreading angle of 6 deg agree with a theoretical an lysis which takes into account attenuation caused by scattered molecules which have been thermally accommodated at the walls of the pparatus. A modified Kantrowitz-Grey system is used to obtain the high-energy beam. Author
