Annual progress report

During the present year, a major effort was put into developing the Mark III detector to be used with the e+e- colliding beams at SPEAR. Data from previous experiments at Fermilab using both neutral and charged particle beams were analyzed, and an approximately seven-month run with the photon beam on hydrogen and deuterium targets was performed. Apparatus for the forthcoming series of experiments using a proton beam with the Chicago Cyclotron Facility at Fermilab was developed and built. The main motivation for all the above experiments was to study the production and decay of states containing charmed quarks. During the coming year a major effort will continue at SLAC with the completion of the Mark III detector and its use in taking initial data. It is anticipated that several years of data taking with the Mark III will be required to obtain a statistically significant number of events of interest. At Fermilab an experiment using a proton beam with the Chicago Cyclotron Facility and a neutron beam in the broad band neutral beam facility will be performed. The data from the previous photoproduction run will be analyzed. In future years at Fermilab, experiments will be performed at increasingly higher energies as they become available. One of the motivations is the possible production of the (weak) intermediate vector bosons by colliding proton and anti-proton beams. For this purpose, a detector for the colliding beams is being developed, as is the so-called FASTBUS system. The scope of the program is best summarized by listing major accomplishments during the present year and the major parts of the program for the coming year.
