The beam line end station, associated instrumentation and dosimetry used at the Indiana University Cyclotron Facility for radiation effects research and testing with up to 200 MeV protons are described. Access to beam for radiation effects studies is greatly enhanced by the capability to share beam with other users on a mikkisecond time scale. Use of shared beam mandates that the beam energy be changed through the use of degraders. Beams degraded by the use of copper degraders are characterized at several locations downstream of thedegradrs where devices may be placed for study.
