Bevatron Operation and Development. XX. Period Covered November, December 1958, January 1959

Book excerpt: Studies of K/sup -/-meson interactions continued, using hydrogen and propane bubble chambers and emulsions. Exposures to emulsions were made in the focused and separated K/sup -/-meson beams for seventeen groups from outside the laboratory, and for two internal groups. The propane bubble chamber was used to investigate pi --meson interactions. Four target bombardments were made for the chemistry gnoup. The location, exit angle, and focus of the deflected pnoton beam were measured. On December 14 the west generator and generator motor were damaged as the result of arcing when the machine was stopped by use of dynamic braking after brush contact trouble was noted on the motor. Bevatron operation was resumed on December 30. (auth).
