Position Summary
The IU experimental nuclear physics group has an active and diverse program addressing fundamental questions in nuclear physics particle physics and astrophysics/cosmology. Group members are leaders in a wide range of experiments including: investigations of the flavor and spin structure of the nucleon STAR at RHIC Belle II at KEK ; studies of parity and time reversal violation between nucleons NIST SNS LANSCE JPARC JLAB FRM measurements of neutrino properties (Fermilab SNS SURF LNGS neutron decay and neutron interferometry NIST LANSCE SNS ISIS ILL and searches for possible exotic spindependent interactions. The group is part of the Center for Exploration of Energy and Matter CEEM at IU which also includes research in theoretical nuclear physics condensed matter and radiation effects studies. Group members include professional staff in electronics mechanical engineering cryogenic design and machinists as well as graduate and undergraduate students. Local facilities include a lowenergy neutron source LENS available for neutron detector development and testing highbay facilities for largescale fabrication professional and student machine shops a polarized 3He lab a dilution refrigerator and a vibration isolated lab for weak force measurement. The laboratory possesses infrastructure on a scale which enables us to make major hardware contributions to experiments. Opportunities are available on all major research projects.
