The 72-in. bubble chamber was successfully operated for the first time in March, 1959 [1]. The bubble chamber is a detector for nuclear particles, and it is presently operating in a beam of antiprotons and π- mesons from the 6-Bev bevatron. The chamber operates with 521 liters of liquid hydrogen which is visible through a 5-in.-thickobiongglass window, 23 in, wide by 75 in. long. The hydrogen in the chamber is at a pressure of 6atm. By quick reduction of this pressure (18 msec) to 3atm, the chamber is made “sensitive” for about 10msec. During this sensitive time, the beam particles from the bevatron enter the chamber and cause nuclear interactions.
