High energy accelerator and colliding beam user group: Progress report, March 1, 1986-February 28, 1987

Work done for the OPAL collaboration at the LEP storage ring being constructed at CERN is reported. The main responsibility discussed is the construction, installation, and maintenance of the hadron calorimeter. Also reported are advances in the design of the OPAL software concerning data handling for the hadron barrel calorimeter. Also reported are experiments at DESY, including a study of electron-positron collisions at PETRA. Experiments at Fermilab are also discussed, including one on deep inelastic muon scattering at the Tevatron II and contributions to the development of the DO detector at Tevatron I. Yet another experiment, this one at Los Alamos, is in its final year of data taking and involves the observation and initial measurement of neutrino-electron elastic scattering. Computer experience in high energy physics is reported. Other activities reported include a neutrino deuterium bubble chamber experiment, and work on a polarized electron storage ring design for HERA. 164 refs., 17 figs
