A desktop supersonic free-jet beam source for a scanning helium microscope (SHeM)

A simple design for an inexpensive, compact, desktop-sized helium free-jet beam source is described. The apparatus, which is Campargue-like in design and utilizes mostly off-the-shelf parts, is capable of producing a centreline intensity of 1.2 × 10^19 atoms per second per steradian. The beam perfor...
