Batavia Accelerator Staff Plans for Bubble Chambers

Plans involving two bubble chambers for the National Accelerator Laboratory at Batavia, Ill. (née Weston) are going forward. NAL officials are exploring with Argonne National Laboratory and the Atomic Energy Commission the possibility of moving the 3.7‐meter hydrogen bubble chamber (photo, left) now under construction at ANL. A decision will be made a year or two before the 200‐GeV machine is turned on. At the same time NAL and Brookhaven groups will design together a very large $(100‐m3)$ hydrogen‐deuterium chamber.
