Medical-Industrial Radiation Facility

The Medical-Industrial Radiation Facility (MIRF) located in the Ionizing Radiation Division of the NIST Physics Laboratory is a user facility for the medical and industrial radiation communities. The MIRF is based on a re-configured rf-powered, traveling-wave electron linac donated by the Radiation Therapy Center of Yale University-New Haven Hospital. The accelerator provides electron energies from 7 MeV to 32 MeV at an average beam current of up to 0.1 mA. In addition, bremsstrahlung generated photon beams are also provided by the bombardment of suitable targets.
