Our experimental heavy ion group is supported largely by the US Department of Energy, and in recent years has consisted of one faculty member, one Senior Research Fellow who works part-time on this project, one full-time and one half-time postdoc, two to three graduate students, and from time to time, an overseas visiting scholar and an undergraduate student. Our physics analysis effort has been focused on multiparticle correlations and particle production using tracking detectors that intercept a large fraction of all particles emerging from the collisions. In the area of detector development, we work on software for tracking and particle identification, various Graphic User Interfaces for monitoring detectors or subsystems, and simulations. In the future, the activities of our group and that of Prof. Spiros Margetis will converge, and we anticipate joint funding and joint advising of some or all of our graduate advisees.
Currently, we conduct collaborative experiments at Brookhaven National Laboratory in New York. The picture shows the 2+ million-pixel E895 Time Projection Chamber installed in a large aperture dipole magnet. Following the recent commissioning of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven, the main focus of our physics analysis has shifted from E895 to a large RHIC experiment utilizing a powerful general-purpose detector system called STAR.
Large-acceptance tracking detectors for heavy-ion collisions need to operate at the forefront of technology in data acquisition, data mining, graphics applications and computers in general, and graduate work in this area builds expertise in widely-applicable techniques as well as providing an excellent training in basic physics. Students in our group have the option to spend an extended period at a national laboratory, where they typically divide their effort among a mix of hardware and software projects according to their personal taste and the responsibilities of our group. Skills can be acquired during this period that help broaden the range of employment opportunities upon graduation.
