1 Comments on Teaching, Advising, and Related Activity

I modified an existing course Physics 215, Computational Mehtods in Physics to include a high-performance computing (HPC) component and take advantage of the advanced computing cluster donated by Martha Carpenter. This new component of the course involved a large investment of time to order and install the cluster (in the Milhiser Computer Center), develop the tools so students could use the cluster remotely from the Physics Department, write new computational laboraties (three) that introduce the physics and technical aspects of using the linux operating system and the cluster tools, and adapt the physics topics of the course to ones appropriate for HPC.

I worked with several of our physics (Musalo and Carbonneau) students during the last year to prepare them for presentations (see highlights) and to counsel them on their future plans.

2 Comments on Scholarship and Professional Development

  1. Electrodisintegration of the deuteron - The deuteron is composed of a single proton and neutron and is the simplest atomic nucleus; making it a unique testing ground for our understanding of nuclei. Our data collected with CLAS at JLab will shed light on (1) the contributions of underlying quarks to the collision which lie beyond `traditional' nuclear physics, (2) a full understanding of the proton-neutron force, and (3) the role of Einstein's relativity. I have completed a draft of a CLAS Analysis Note that is being rewritten in response to comments from collaborators. This is the first step in the process for publishing this work.

  2. Magnetic Form Factor of the Neutron -The elastic electromagnetic form factors are the most basic observables that describe the internal structure of the proton and neutron. I am part of the analysis effort to extract the magnetic form factor of the neutron from scattering data collected at JLab on deuterium. We have already published the first results in Physical Review Letters. We have also begun the analysis of more data on the neutron magnetic form factor that will extend the range of our understanding of the electromagnetic structure of the neutron.

    I am the leader of an experiment (with an A- rating) to extend these measurements more deeply into the interior of the neutron. We have been developing simulations and predictions to prepare for the experiment. It is part of the scientific program of the 12 GeV Upgrade at Jefferson Lab which will expand the physics opportunities there. The 12-GeV Upgrade is now the highest priority project in nuclear physics in the United States. We are developing software for the simulation, reconstruction, and analysis of CLAS12 data. A Momorandum of Understanding between Jefferson Lab and the University was signed in spring, 2012.

  3. Bose-Einstein Correlations at the Electron-Ion Collider - The United States is one of the world leaders in Nuclear Physics and to maintain that status we have begun thinking about the next generation of accelerators after Jefferson Lab. The Electron-Ion Collider (EIC) will smash together beams of electrons and atomic nuclei to probe nuclear matter at extremes of size, temperature, and density in ways never attained before. I am the author of a chapter in a white paper making the scientific case for the EIC. In particular, I have simulated the formation of quantum mechanical, `entangled' states (Bose-Einstein Correlations) that could be detected at the EIC to yield clues about the size, shape, and temperature of the fireball formed in the collision. This work reveals that we will be able to map the properties of extreme nuclear matter by measuring these correlations. This work was published as "Gluons and the quark sea at high energies: distributions, polarization, tomography", D.Boer, ... G.P.Gilfoyle, et al. arXiv:1108.1713v2 [nucl-th].

  4. A Supercomputing Cluster at the University of Richmond - This computing facility is our main scientific instrument and is constantly used by my students and me during the summer and during the academic year. It is also used by my collaborators at JLab. All this work has resulted in a publication in the Journal of Physics.

  5. Data Collection - One of my responsibilities as a member of the CLAS Collaboration at JLab is to fill data collection shifts. This involves monitoring and controlling the experiment in eight-hour shifts. I took eight shifts during the last year including four as shift leader.

  6. Online Recsis - The data acquisition system for the CLAS detector collects about 1000 GByte of data per day. The data we collect are complex and require many years of analysis before they are ready for publication. To monitor this deluge of information I developed software that does a full analysis on a subset of the data during the experiment. The results are immediately posted on the web so experimenters can see in realtime the quality of the data.
