摘要：
A short-pulsed (less than 1 ms) compact supersonic helium beam source has been developed for plasma diagnostics purposes. The beam has been characterized experimentally and the results compared with calculations from a simple model that takes into account interaction between the supersonic beam and gas in the region between the nozzle and the skimmer. For a 200 mu s driving pulse, a beam of density N > 1 x 10(18) m(-3) on the axis, a width of D approximate to 1 cm at a distance of 30 cm from the nozzle and a Velocity upsilon approximate to 1.8 x 10(3) ms(-1) has been achieved.
