The National Accelerator Laboratory (NAL) asked the Stanford Linear Accelerator Center (SLAC) to design and implement the expansion system for the IS-foot bubble chamber. This report describes some of the basis for the design and details the equipment which has been constructed. The SLAC Bubble Chamber Group has had experience at Lawrence Radiation Laboratory, Berkeley, and at SLAC with several chambers with a total of over 50 million expansions. The design for NAL is directly scaled from the SLAC 82 11 chamber (former Lawrence Radiation Laboratory 72" chamber) and the SLAC 40" hydrogen bubble chamber. These chambers use resonant hydraulic expansion systems with partial pneumatic control systems. "Tuning" the resonance for the different chamber operating liquids (hydrogen, deuterium, neon) is accomplished by changing the mass of the "bouncer" piston which serves as a mass multiplier in the resonant system. At this point in time all the components have been designed, assembled, and checked out at SLAC. Previous experience with these systems indicates extensive tests and modifications are usually necessary for successful routine operation. These test are scheduled to begin in December 1971 at NAL with the expansion actuator and all support equipment installed in its final position.
