RESEARCH ACTIVITIES

Fermilab Experiment 853 (1995-present) The primary goal of this experiment is the determination of the feasibility of extracting a primary beam for use in fixed target experiments in manner which is non-perturbative to the simultaneous running of collider experiments. The extraction is performed by inserting a bent silicon crystal in the halo of the circulating stored beam at the Fermilab Tevatron. For this experiment I have been involved in analysis of data taken in the previous runs to determine the extraction efficiency and alignment reproducibility of the crystal. Fermilab Experiment 771 (1989-present) The primary goal of this experiment was the study the production of hadrons containing b quarks---paired with lighter (u,d) quarks---by an 800 GeV/c² proton beam on a fixed silicon target. Due to the expected low cross section for these events at this energy, the experiment was designed to trigger on events containing a high mass di--muon pair or a single high transverse momentum muon. Considering theoretical predictions for the cross section times branching ratio into these distinctive signatures, and the computed acceptance of such events into the experimental apparatus, only one in 10¹¹ interactions were expected to be recorded in our final data sample. The experiment was therefore run at high rates. My contributions to E771 encompassed almost each aspect of the experiment. I was a central figure in the revitalization of each element of an electromagnetic calorimeter and its electronic readout, and in setting timings and gains. I was also involved in building a silicon micro--vertex detector, setting up triggers, developing online monitoring code, and building and monitoring the experiment's fast data acquisition system. The event selection criteria gave the experiment a large sample of c c-bar bound states, which allowed us to study the spectroscopy of a number of bound states below the open charm threshold. My contributions to the offline data analysis were primarily in the electromagnetic shower reconstruction in the electromagnetic calorimeter. The detector had five major components, including sampling calorimeters, lead and scintillating glass blocks---totalling of 1,600 channels. The data analysis involved an offline energy calibration of each element of the detector, a relative alignment of each component, an absolute alignment of the device relative to the spectrometer, a time calibration of 400 channels, resurrection of old shower reconstruction code, and code development for the reconstruction of electromagnetic showers. Furthermore, I participated in the computer simulation of the entire E771 detector, and was sole author of a detailed simulation of the E771 electromagnetic calorimeter---each within the framework of the GEANT Monte Carlo simulation package. My analysis included spectroscopy of c c-bar and a measurement of the branching ratio for the rare decay

. LEGS (1986-1989) The ``LEGS'' beamline (Laser Electron Gamma Ray Source) was a tagged photon beam created by Compton backscattering UV photons off electrons in the National Synchrotron Light Source X-ray storage ring. The photon energies were tagged by measuring the recoiling electron momenta in an electron spectrometer. My contributions to the group included building a flip coil probe and using it to measure the field components of a modified sextupole magnet used in the storage ring. I assisted in building, testing, and field mapping two dipole septum magnets, used in the electron spectrometer. I was also responsible for the construction of a phoswhich detector system used in the measurement of the ratio E2/M1 for the proton. BNL (1985-1986)

At the Brookhaven's National Synchrotron Light Source, I assisted a solid state X-ray scattering group in building and testing an X-ray beamline. Here I developed expertise in ultra-high vacuum techniques.

TEACHING EXPERIENCE

During the academic years of 1989-1990 and 1990-1991, I taught a Catholic Chrisitian Doctrine course. In addition, I have logged numerous hours of private and professional tutoring, have directed junior graduate students and undergraduate students in research projects, and have lectured in local public schools both in Virginia and Illinois.

PERSONAL INFORMATION

In addition to physics, my interests have included co-founding a soccer club and later a rugby club. I've actively played rugby for 15 years and have been president, capitain, and assistant coach. I've also coached a women's college rugby club. Of equal interest to me is music. I've sung as a church cantor for five years, have sung semi-professional opera, and have appeared as soloist with choral groups both in the U.S. and in Europe.
