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° 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.
Anferov VA, Ball M, Friesel DL, et al., 2001, Dispersion suppression in the MPRI achromat beam line, Pages: 2488-2490
The first section of the beam transport system for Mid-west Proton Radiation Institute (MPRI) has been constructed. It is designed to compensate both spatial and angular dispersion of 205 MeV proton beam coming out of the Indiana University Cyclotron. We present data obtained during the commissioning of the beam line including measurements of the beam dispersion and the beam emittance out of the cyclotron.

Ball M, Brabson B, Budnick J, et al., 1999, Beam motions near separatrix, Pages: 1548-1550
Experimental data on particle motion near the separatrix of the one dimensional (1-D) fourth-integer islands are analyzed. When the beam bunch is initially kicked to the separatrix orbit, we observed a strong decoherence in the coherent betatron motion. We find that, through intensive particle tracking simulation analysis, the decoherence has resulted from the beam being split into beamlets in the betatron phase space. However, we also observe an unexpected recoherence of coherence signal, which may result form a modulated closed orbit or the homoclinic structure near the separatrix.
Jones WP, Berg GPA, 1999, Design of a beam transport system for a proton radiation therapy facility, Pages: 2519-2521
A new beam transport system has been designed to bring the 210 MeV proton beam from the Indiana University Cyclotron to four proton therapy treatment rooms. The main trunk line will be achromatic and employ a fast beam splitting system to allow treatments simultaneously in different treatment areas. To enhance flexibility of operation, each treatment room will have its own energy degrader and energy selection system. There will be two treatment rooms with a fixed horizontal beam line. The first will be an upgrade to our current eye treatment facility and the second will be designed for head, neck, and brain treatments including stereotactic radiosurgery. In addition, there will be two rooms with iso-centric gantries for more complex multi-port treatments.

Derenchuk VP, Kupper RR, Petri HR, et al., 1998, Pulsed ion source for the IUCF Cooler Injector Synchrotron, Proceedings of the IEEE Particle Accelerator Conference, Vol: 3, Pages: 2737-2739
A pulsed source of H- ions has been constructed with minimal cost and is currently being used for commissioning of the Indiana University Cyclotron Facility (IUCF) Cooler Injector Synchrotron. A commercially available duoplasmatron, previously used with the IUCF cyclotrons, was modified for pulsed operation and has produced 25 keV H- ion beams of up to 1 mA in an emittance of less than 0.38 π-mm-mrad normalized (80%) and can operate up to 10 Hz with 50 μs to 4 ms pulse length. A simple and economical pulsed high-power MOSFET circuit is used to drive the arc and the gas valve. The beam transport line to the 7 MeV RFQ-DTL, features an Einzel lens doublet immediately upstream to match the beam from the source. The design, development and performance of the ion source and beam transport line is presented.

A five-scalar probability density; function (pdf) transport equation is applied to the calculation of a premixed turbulent counterflow jet configuration. The mixing term in the pdf equation is represented alternatively by a coalescence-dispersion model and by the linear mean square estimation closure. The chemistry is described by the reduced reaction scheme of Jones and Lindstedt [1]. For the velocity held, the full time-dependent forms of the governing equations (written in cylindrical polar coordinates) are soh-ed and the k-epsilon model is used to represent turbulent transport. Calculated profiles are compared with the experimental data of Mastorakos et al. [2,3]. The observed flame structure and the measured profiles of velocity and the major species are reproduced to a good accuracy by the computations. However, in the case of carbon monoxide, the predicted levels are in less satisfactory agreement with measured values, and, under fuel rich conditions, CO levels are somewhat over predicted.
