Continuation of support for the Intercampus Institute for Research at Particle Accelerators. Final technical report

During the budget period beginning May 16, 1995, the UCSD group of the U.C. Intercampus Institute for Research at Particle Accelerators devoted approximately 75% of its effort to the PEP-II B Factory and the associated BABAR detector at SLAC, and 25% of its effort to the LSND collaboration at LAMPF. Michael Sullivan spent all of his time on PEP-II, while Alan Eisner split his time between BABAR and LSND. Sullivan remained a critical member of the group designing the PEP-II interaction region and the machine-detector interface; and, in fact, toward the end of the period he left IIRPA to become a SLAC employee, in order to ensure his continued participation in those efforts. That work has focused on developing an interaction region in which the accelerator can achieve the required high specific luminosity while, at the same time, maintaining low enough beam background to allow a detector to operate. Both requirements are essential to achieving the primary physics goal of not only detecting but doing detailed measurements of CP violation. Eisner`s work on the BABAR detector concentrated on the electromagnetic (CsI crystal) calorimeter. With the calorimeter geometry largely established, he turned his attention more fully to the areas of calorimeter data acquisition and calibration. The data acquisition focus, was on understaning the performance of the proposed system via calculations and simulations, a joint project with Yao-xin Wang of the UCSB IIRPA group
