摘要： A pulse nozzle of a reaction apparatus which obtains a very low temperature by expanding high-pressure and normal-temperature gas in heat insulation manner includes a fixed slit member disposed at an inlet of the nozzle and having a plurality of slit openings, a movable slit member having similar slit openings disposed along the fixed slit member, and two piezoelectric-crystal elements driven by an external pulse signal to slidably move the movable slit member with respect to the fixed slit member repeatedly to thereby open and close a flow of gas in the pulse manner. A plurality of the pulse nozzles are disposed in parallel to increase the capacity of the pulse nozzle.
