Bevatron Operation and Development, VI

A large fraction of the effort on high-energy physics this quarter was devoted to the study of K particles. Ten of the fourteen external laboratory groups, as well as seven of the internal laboratory groups, used the K{sup {+-}}-beam facilities. These experiments included measurements of lifetimes, modes of decay; and excitation functions. Counters and cloud-chamber techniques were used in addition to nuclear emulsions. Measurements of total and differential cross-sections for {pi}{sup -} mesons continued. Work on proton-proton scattering was extended to 4.8 Bev. Radiochemical investigations of spallation products in light and heavy elements were extended. A new target plunger, a 4-inch quadrupole magnet, and two new steel collimators were added to the experimental facilities. Accelerator development this quarter included experiments on increasing the acceptance time of the Bevatron, self-tracking of the radiofrequency equipment, and the substitution of an analogue computer for the 3D-point curve corrector
