Abstract

A pulsed-gas jet with interesting properties has been developed. A typical pressure obtained at the output of this pulsed-gas jet is 25 Torr for a backing pressure of 150 Torr. At a repetition rate of 10 Hz, the background pressure stays below 1.5×10−4 Torr. Laser-induced fluoresence measurements permit one to determine the pressure and the divergence of the gas jet accurately.
