CONTROLLED SENSITIVITY BUBBLE CHAMBER WITH STABILIZED FINAL PRESSURE
ABS>A radiation sensitivity stabilized 2-liter bubble chamber operating with CBrF/sub 3/ or fluorocarbon gas-liquid mixtures near room temperature is described. Final pressure stabilization is achieved by a method first suggested by Blinov et al. Flat bottomed pressure pulses 30 ms long, and corresponding bubble density plateau with bubble density variations smaller than plus or minus 5% were obtained. The chamber sensitivity is reproducible at any time and can be adjusted instantaneously to the desired bubble density. The chamber is also temperature stabilized. Accurate bubble counting for particle velocity determinations is possible without reference track in each bubble chamber picture. A discussion is presented on how to minimize undesired pressure oscillations and on the possibility to pressure stabilize much larger chambers. (auth)
