Abstract
A precision liquid hydrogen bubble chamber with rapid cycling capabili ty and a photographed volume of 150 x 70 x 50 mm(3) has been construct ed to study short-living elementary particles. Its refrigeration syste m is operated with liquid helium. The chamber body, manufactured from the polycarbonate Lexan(R), is almost free of vibrations due to the in novative expansion system with two pistons operating in opposite direc tions. The chamber operates with 5 ms cycle time and a rate up to 30 s (-1). The chamber has already been cycled 6.7 million times and about 0.3 million pictures have been taken. At the hydrogen temperature of 2 9.8 K a track density of 150 bubbles/cm has been achieved with bubble diameters of 25 mu m
