Nuclear Physics Research with Polarized Photons and Protons

1. Nuclear Physics Research with Polarized Photons and Protons Faculty: R. Miskimen (miskimen@physics.umass.edu) Postdoc: A. Teymurazyan Grad. students: C. Harris, P. Martel, D. VonMaluski Undergraduates: R. Rines Engineer: D. Lydon (Astro.) Development of new semiconductor photo-detectors for applications in nuclear/particle physics, medical imaging, and homeland security. † “Large area” photo-detectors, ~1 cm2, with integrated waveform digitization (ADC), for direct replacement of photomultiplier tubes. Purely digital detectors. Photo-detectors with good sensitivity at the ~1° K level, for use in polarized proton targets, future applications in dark matter searches Worlds largest solid-state photomultiplier, 51,000 pixels, 30 mm x 30 mm PRIMEX lead-tungstate calorimeter † In collaboration with Radiation Monitoring Devices, Inc.

2. II. Nuclear physics with polarized photons and protons at the Mainz Microtron, Germany • Mainz is a city of ~200,000, located on the Rhine, best wine region in Germany, the beer is also good • Polarized Compton scattering to study the “long distance” spin-structure of the proton • Polarized threshold p0 photo-production as a test of low-energy QCD. Crystal Ball detector Polarized proton target

3. Research support is available for students who want to work in a lab learn about detectors and electronics enjoy good German wine and beer
