Conclusions from M. Durante • The future of particle therapy strongly depends on improvements in medical physics • Reduction of range uncertainty is mandatory and strategies beyond fiducial markers and gating/rescanning should be found (tracking, online monitoring, proton radiography) • Beam deliver technologies (including 4 D/5 D optimization) to broaden the diseases elected to be treated with particles is very important to reduce the cost/benefit ratio of the facility • New ions can be use for pediatrics (4 He) or very hypoxic tumors in single-fractions (16 O) but require preliminary nuclear physics measurements (attenuation, fragmentation) • BNL would be the ideal facility for this research, urgently needed in US in relation to the NCI P 20 now ready to start

Opportunities for NSRL/BNL from K. Held • Additional facilities/capabilities – Scanning pencil beam – “Higher” dose rates than currently available with some ions – Imaging • Training and education

NSRL • • Large, uniform beam. 0 - 1000 Me. V/n at the target. Ion chamber and scintillation counter dosimetry. Can work with any ion EBIS can deliver + protons

Second Beam Line? • To do things NSRL cannot: – Small pencil beam (1 -5 mm fwhm). – Scanning. – Off axis imaging equipment. – Accommodate more complex setups.

Second Beam Line • • • Parallel to existing line. Up to 500 Me. V/n. Small beam (1 -2 mm) Scanning (? ). Share Support and Control Building.

Second Beam Line • • Up to 500 Me. V/n Small beam (1 -5 mm) Scanning (? ) Large target room – Room for TOF measuremnts – Room for imaging equipment – Distance from walls Draw Back: requires new support building.

Beyond Construction • Passing what we have gathered over the years – Training the next generation – Experimenting and testing – Developing techniques • Ions, extraction, beam structure, gating, etc. • Scanning. Monitoring position, dose and depth. – Developing instrumentation

Bio-Medical Sand Box • Proposing to create a place for research and developments in radiation therapy – in collaboration with universities(? ) – Beam line design – Nozzle design – Instrumentation – Scanning – Collimation – Biology

The Model • Some beam line or capability funded by DOE • Operated with NIH (NCI) funding, or a combination of DOE/NIH • No beam time charge to users
