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.
