In the past year, our research program encompassed four major areas: the UA-6 experiment at CERN, the CDF (Collider Detector at Fermilab) experiment at Fermilab, the SDC (Solenoidal Detector Collaboration) experiment of the SSC (Superconducting Super Collider), and an R&D project for the development of High Pressure Gas Calorimetry for high luminosity colliders. The UA-6 experiment studies direct-{gamma} and J/{psi} production in pp and {bar p}p interactions at {radical}s = 22.5 GeV. In the CDF experiment we have concentrated in the plug calorimeter upgrade program, which involves replacing the plug and forward calorimetry with a more compact calorimeter based on scintillator tiles being readout with wave-length shifting (WLS) fibers. In the SDC experiment, we have taken primary responsibility for the Preshower/Shower-Maximum detectors. We wrote the original shower-maximum proposal for the SDC and have contributed to detector simulations, scintillator/WLS-fiber light yield measurements, building prototype preshower and shower-maximum detectors and measuring their performance in a test beam, and developing novel photosensitive devices to read out the fibers. The High Pressure Gas Calorimeter project has been very successful. A prototype parallel plate iron based electromagnetic calorimeter was designed, constructed and tested in an electron beam at Fermilab. The results were very encouraging. We are presently working on a new design, which would be more suitable for the construction of economical, large scale calorimeters, such as those needed for the forward region of SDC and FAD.
