ASTROPHOTOGRAPHY and RELATED RESEARCH STUFF from JAMES M. HOFFMAN
I am a physics and astronomy student at Stony Brook University. My previous work experience was on the forward preshower (FPS) detector for the DØ upgrade at Fermi National Accelerator Laboratory in Chicago. This experiment investigates proton-proton interactions at very high energies. This work consisted of constructing, calibrating, and certifying of modules for the North and South Layers of the detector. The work was performed at Brookhaven National Laboratory in Upton NY.
I am currently working on the ATLAS project which also investigates proton-proton interactions at the LHC (Large Hadron Collider) at CERN in Geneva. I am part of a team that is performing destructive tests which will investigate internal and external corona. Corona is a repetitive charging and discharging of electrical conductors within a substance. I'm also heading up the team for the High Voltage Filter Modules that will be housed above the Feedthrough Ports. Currently I am conducting destructive tests that will allow us to be aware of the effects of a full calorimeter discharge across each individual High Voltage filter. The worst case scenario would be approximately 6 micro farads at 5 kV. My other duties include working on the IRC resistive networks that will be housed in the end cap calorimeter in the ATLAS experiment.
I will also be starting work on the RHIC (Relativistic Heavy Ion Collider) project very soon. The focus of this experiment is to study proton-proton (pp) scattering using both polarized and unpolarized beams. The experiment will study pp elastic scattering from 60 GeV to 500 GeV in two kinematical regions, Coulomb Nuclear Interference (CNI) and the medium region. Most of my work will be with the silicon tracker team.
