Optimal proton radiation treatment of tumors having broad regional-disease patterns of spread places specific design requirements on the synchrotron and switchyard at Loma Linda University Medical Center. The purpose of this project is to perform engineering upgrades to the synchrotron accelerator and switchyard to permit the delivery of therapeutic proton radiation with the essential beam characteristics needed to treat such tumors. The modified design will permit modulation of beam energy on a spill-to-spill basis and delivery of uniform beam intensity over an extended extraction period. The project scope includes enhancing the extracted beam intensity control developing software applications to provide dynamic accelerator energy changes for achieving spill-to-spill beam delivery and developing an integrated fast beam cut-off system to safely inhibit proton beam from scanning outside the targeted volume. To date, significant progress has been achieved on most of the major tasks described in the grant proposal, including development of hardware and software requirement specifications and design documents. The research and design work for the remaining tasks will be completed in the first half of next year, and system integration will follow.
