Nuclear Physics and Applications

Operation of the Alvarez 4-in. hydrogen bubble chamber in a high-energy photon beam is described, the techniques employed in several modes of operation are discussed, and the corresponding bubble chamber conditions are tabulated. Reduction of electron background was accomplished by beam hardening and by using a Mylar beam-entrance window on the chamber.
