Abstract
A double-loop helium refrigeration system is developed to stabilize th e operating conditions of a liquid-hydrogen rapid-cycling bubble chamb er. The system makes it possible to reduce the amount of liquid hydrog en used to a minimum and thus to localize the dangerously explosive zo ne within the boundaries of the vacuum housing. Under operating condit ions, the system maintains temperature and pressure to an accuracy of +/-0.005 K and +/-0.01 atm, respectively, Consumption of liquid helium is within 60 1/day.
