A High Density Neutral Gas Jet Target as a Windowless Stripper
A windowless gas target has been developed which uses gasdynamical focussing of a supersonic jet expanding into a region of static pressure of about 1 Torr. Target thicknesses between a few ¿g/cm2 and about 200 ¿g/cm2 can be achieved. Continuous density measurement can be made by means of electron scattering or light attenuation.
