Book Description
The design considerations, engineering details, and beam survey data relevant to a shock-tube-driven molecular beam are presented in detail in this report. The survey data are for an N2 beam with a kinetic energy per molecule of 1.3 ev, and two Ar beams of 1.4 and 2.2 ev. The spreading angles of these beams are of the order of 1 degree. Sufficient engineering details are presented to show how all the elements of the apparatus, including a target beam, function and how they are synchronized with the firing of the shock tube. (Author).

Book Description
The preliminary development of a high intensity molecular beam, in which a small tailored interface 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 pilot apparatus. The intensity of 2.5 x 10 to the 18th power molecules 1/sq.cm./sec. and the spreading angle of 6 deg agree with a theoretical analysis which takes into account attenuation caused by scattered molecules which have been thermally accommodated at the walls of the apparatus. A modified Kantrowitz-Grey system is used to obtain the high-energy beam.

Book Description
The development of an intermittent target beam system for use in conjunction with the CAL shock-tube-driven molecular beam is reported. The beam is 1 inch in diameter and has a density of approximately 4 x 10 to the 12th particles/cu cm. A room-temperature source is used. The operation of a mass spectrometer in the environment of a 2.14 ev argon beam has also been studied and it has been found necessary to employ extensive shielding of the instrument from residual ionization, radiation and background scattering.
