Senior Mark Moog is part of a team that is preparing for the “12 GeV Upgrade” at the Thomas Jefferson National Accelerator Facility in Newport News. The upgrade is a $300 million project at Jefferson Lab to explore new territory within the atomic nucleus. Mark has been performing sophisticated simulations of a new detector which will be used in experiments to measure the internal structure of the neutron, a project lead by professor Jerry Gilfoyle. Mark traveled to Santa Fe, NM, this fall to present his work at the fall meeting of the Division of Nuclear Physics of the American Physical Society.
