The Indiana University midwest Proton Radiation Institute

Funding to convert the IUCF K220 separated sector cyclotrons into a dedicated proton source for Cancer Therapy was released by Indiana University in August of 2000. Phase I of the Midwest Proton Radiation Institute (MPRI) will initially consist of the IUCF separated sector cyclotrons upgraded to operate at a fixed energy of 205 MeV, a treatment room containing both a general purpose large field horizontal fixed line and a small field line for the treatment of eye melanoma, a second treatment room with a 360/spl deg/ rotating gantry, and a comprehensive medical clinic. A third treatment room with a gantry is incorporated into the beam delivery system design as a future upgrade. The MPRI beam delivery system is now under construction and will incorporate a beam sharing system to allow simultaneous beam delivery to all medical treatment rooms, as well as to medical and commercial research facilities. Additional Funding is anticipated for the construction of a dedicated Radiation Effects Research (RERP) facility for NASA and other commercial users requiring beam similar to those used for proton therapy. This report will outline the goals and design of the MPRI medical and commercial facilities, its present construction status and projected completion schedules.
