A large MULANA based analysis package, written in FORTRAN, for computing the cross section for proton - nucleus collisions at 400 GeV/c momentum from data taken in experiment E609 at FNAL, was implemented on a Z-386, 16 MHz microcomputer workstation featuring an 80 Mbyte hard drive, and a three Gbyte 8-mm Exebyte tape drive, based in the Ball State High Energy Physics Laboratory, in a feasibility study of conducting such analysis on a workstation as a viable alternative and/or adjunct to the Ball State University VAX system. One of 40 large 1600 bpi 9-track data tapes from Experiment 609 provided the data file for the computation. The analysis package was first run on the VAX system. Special problems solved in connection with using the software package included converting the large data file to a suitable form for use at the workstation, transporting that file from the VAX to the workstation, modifying the VAX FORTRAN software package for implementation in the OS/2 workstation operating system environment, and graphical exposition of the results. With the results of conducting the analysis on the VAX system serving as a benchmark, it was determined first that the quantitative analysis results were identical, second, that computing times were similar, and third that the workstation provided unique conveniences. Overall, the results showed that the workstation is a reasonable alternative to using the VAX for High Energy Physics analysis work but also suggest the attractiveness of using similar but faster workstations in the near future. / Department of Physics and Astronomy

This study presents a comprehensive overview of the significance and results of implementing a data analysis for the calibration of an iodine neutrino detector. Previous neutrino detectors have failed to confirm the standard solar model or settle the question of a massive neutrino. An iodine detector, which was proposed in 1988, is being constructed to hopefully resolve these issues. Before the iodine detector can give conclusive results, it must first be calibrated. Because there is no standard neutrino source, these calibrations must be done indirectly. The method for calibrating the 127-Iodine detector is by using a (p,n) reaction at 0' on an iodine target and a proton beam provided by the Indiana University Cyclotron FacHity (IUCF). When a neutrino is captured by 127-Iodine, the nucleus becomes an excited state of 127-Xenon at an energy of 125 keV. By measuring the Gwnow Teller strength fimction of the transition from the ground state in 127-Iodine to the 125 keV excited state in 127-Xenon, the iodine detector can be suitably calibrated. / Department of Physics and Astronomy

The HERA accelerator, an electron-proton collider facility based at the DESY laboratory in Hamburg, started delivering luminosity to the ZEUS experiment in May 1992. The short time of 96ns between bunch crossings and the fact that the primary source of detector activity in ZEUS does not come from the e-p interactions of interest but rather from other sources makes a high performance three level trigger system essential to data-taking. We present one part of the ZEUS trigger system, the Central Tracking Detector First Level Trigger (CTD-FLT). The principle of operation and the hardware implementation are discussed at length. A prototype system which was used during the early stages of ZEUS data-taking is described. We detail the principles of the CTD-FLT hardware testing and discuss aspects of the First Level Trigger data from the 1993 running period. During this time the CTD trigger has proved to be an invaluable part of the overall system. The high energies accessible at HERA make it possible to probe a variety of new physics models. The second part of this thesis focuses on one such model - Supersymmetry (SUSY). After an introduction to the model, a search for R-parity violating SUSY in the ZEUS data from the 1992 running period is described. No evidence for such signals has been found and hence we set upper limits on the mass scale of the theory. Finally we present a Monte Carlo study of the potential discovery reach of HERA for R-parity violating SUSY models, and come to the conclusion that HERA is an ideal place to look for such phenomena.

The technical implications are discussed, of the physical principles behind ISIS, a large volume nuclear particle detector. The particular solution adopted in ISIS is described, for the accurate acquisition of data at high rates and under poor signal-to-noise conditions. A computer program has been written to simulate the processing of signals and noise within ISIS. To check the validity of the simulation, its predictions have been compared with the results of experiments using prototype equipment. With the aid of the simulation, the performance of ISIS has been investigated as regards the spatial resolution and the particle-identification capability of the device. An optimum design for the whole ISIS device has been attained, as a compromise between this performance and tolerable systematic effects. In addition, it has been shown that, around the operating point, there is an adequate window within which satisfactory performance is maintained.
