Physics Department Mission /overview
Our mission: The mission of the Idaho State University Department of Physics is to pursue cutting edge research in both fundamental and applied physics, and train of the next generation of physical scientists, technicians, and educators.
- Overview
The Idaho State University Department of Physics is actively engaged in a variety of cutting edge research pursuits, all of which focus on the use of experimental nuclear physics techniques to address problems in both fundamental and applied science. Major efforts include:
- nuclear non-proliferation and homeland security
- radiation effects in materials and devices
- nuclear reactor fuel cycle physics
- accelerator applications
- biology
- fundamental nuclear and particle physics.
Clean Room
The Idaho Accelerator Center and ISU's Department of Physics are building detectors for an upgrade of Jefferson Lab's Hall B. The detectors are wire chambers containing approximately 5,000, 30 micron diameter wires that are used to form gaseous cells which can detect the passage of ionizing particles. The 2 year long project will construct detectors that are about 6 feet high and will eventually be installed at Jefferson Lab in Newport News, Va. The detectors will be part of a larger detector that will be used by a group of more than 100 physicists to perform fundamental nuclear physics measurements.
The Idaho Accelerator Center (IAC)
The Idaho Accelerator Center (IAC) is a research facility operated by Idaho State University located in southeast Idaho. It provides opportunities for scientists and engineers from the University, the private sector and the national laboratories to utilize specialized nuclear facilities. It serves as a principal investigating conduit for R&D in nuclear physics applications in materials science, biology, homeland and national security. Student's from the Physics department are involved in all aspects of the center, from operating electron accelerators to performing experiments in nuclear physics applications.

Nucleon's Fractional Down Quark Polarization
The contributions of a nucleon's constituents, quarks and gluons, to the spin of the nucleon has been a long standing question since the 1980s when it was first observed that quarks contribute less than 40%. The spin physics program at ISU is working to measure the contribution of a nucleon's down quarks to its spin. This is referred to as the down quark fractional polarization. Measurements of this quantity when compared with the standard theoretical description of quark interactions, Quantum Chromodynamics, have yet to indicate a transition from the observed negative values to the predicted positive value. One goal of ISU's spin physics program is to determine the veracity of the theoretical prediction through a series of measurements with the expected precision shown above (CLAS12).
