High-energy physics progress report, 1983-1984

The scientific work which has engaged our attention in the last eight to ten months is outlined: (1) lifetime measurements of the D+ and D0 mesons; study of charm photoproduction mechanisms; (2) study of the radial excitation of vector mesons; (3) other spectroscopy of light quark systems; (4) particle production mechanism at high energies; (5) monitoring systems for lead-glass detectors at BNL and Fermilab; (6) further tests of new concepts for bubble chamber operations; and (7) shifting of operation to modern VAX computer system. Details of this work are given
