	The University of Washington Medical Cyclotron Facility (UWMCF) is built around a Scanditronix MC-50 compact cyclotron that was commissioned 1983 and that has been in continual use since. Its primary purpose is the production of 50.5 MeV protons for fast neutron therapy. While this proton energy is too low for proton therapy, it is ideal for research in small animal models. In addition to the protons used for fast neutron therapy and proton therapy research, UWMCF is able to accelerate other particles at variable energies. This makes it ideal for medical isotope research, including isotopes such as 211At, 186Re, and 117mSn that are being developed to target and treat metastatic disease at the cellular level. Most recent upgrades to the facility have been to the control systems. The original accelerator and therapy control systems were run on a DEC PDP-11 with a custom centralized i/o system built around the Z80 processor and chipset. Over the last 10 years we have continually been upgrading the controls while remaining operational, moving to a distributed system developed with the open source Experimental Physics and Industrial Control System (EPICS) toolkit.

The University of Washington Medical Cyclotron Facility (UWMCF) is built around a Scanditronix MC-50 compact cyclotron that was commissioned 1983 and that has been in continual use since. Its primary purpose is the production of 50.5 MeV protons for fast neutron therapy. While this proton energy is too low for proton therapy, it is ideal for research in small animal models. In addition to the protons used for fast neutron therapy and proton therapy research, UWMCF is able to accelerate other particles at variable energies. This makes it ideal for medical isotope research, including isotopes such as 211At, 186Re, and 117mSn that are being developed to target and treat metastatic disease at the cellular level.
