This document discusses the non-scaling FFAGs in the UK, specifically focusing on the EMMA and Proton Therapy Machines. It provides information about the EMMA project, its location, funding sources, and the latest UK plan. It also outlines the next steps for EMMA and the Proton Machine, including understanding tracking results, preparing for a BT proposal, and identifying necessary R&D.

EMMA Non-scaling FFAGs in UK • Requirement for (at least) one non-scaling FFAG clear: - multi-resonance crossings - huge/tiny momentum compaction - asynchronous acceleration • Original idea: build electron modelEMMA: - Model of muon accelerators from US Study 2a - Sufficient flexibility for detailed studies • Baseline design done • Selected lattice: - 10 to 20 MeV - 42 cells, doublet lattice - 37cm cell length - ~16m circumference - RF every other cell - 1.3GHz, TESLA frequency • Specification of hardware started
EMMA Non-Scaling Electron Model EMMA
EMMA Energy Recovery Linac Prototype at Daresbury Laboratory EMMA Location Need somewhere with flexible injector: - variable energy - variable bunch structure - ~1.3GHz Experimental hall Infrastructure
EMMA Funding • Possible sources of funding for EMMA identified: PPARC – unlikely, has already funded MICE Basic Technology Fund UK Gov Spending Review Europe – tried and failed CCLRC • BT, SR and CCLRC need generic (i.e. non-PP) project • Campaign for hadron therapy support undertaken • Too successful!See next……..
EMMA Proton Machine • New Dept of Radio Oncology forming in Oxford • Has £3M and can get 2x more for “right” machine: - protons - >40 MeV required; ~100 MeV desirable - must fit in new building being built - carbon interesting if reasonable energy & possible • Very interested in non-scaling FFAGs - not interested in cyclotrons, synchrotrons, etc • Machine should be hadron therapy prototype in 2 ways: - study of therapy using mice (hence >40 MeV) - demonstration of use of non-scaling FFAGs
EMMA Latest UK Plan • Build both EMMA and proton machine! • “Independent” funding routes: proton: Medical Research Council & Cancer Research UK EMMA: UK Basic Technology Fund/CCLRC • Link together in BT proposal • Emphasis still on hadron therapy • Complementarities: proton: hadron therapy prototype; low beta EMMA: detailed study of non-scaling optics; model of NF accelerators training machine; high beta
EMMA Next Steps - EMMA • Need to understand tracking results: - Are Francois and Shinji seeing the same effect - If so, is there a problem with trans. acceptance - If so, how do we fix it • Preparation for BT proposal: - Deadline around April 2006 - Need demonstration of feasibility from tracking - Need complete layout, including injection, extr. - Need diagnostics • Need reasonable cost estimate: - better RF cost (underway) - better magnet cost - injection and extraction cost - diagnostics cost - etc!!!
EMMA Next Steps – Proton Machine • Needs a name! Two candidates so far: FAMOUS - FFAG Accelerators for Medical and Other Uses PROMETHEUS – PROton Medical THErapy USes • Need to write proposal to access funding: - timescale ~< 1 year - demonstrate advantages of non-scaling FFAGs for hadron therapy - demonstrate feasibility of proton prototype • Need at least one lattice this week: - Linear or non-linear? - Doublet, FODO, triplet, pumplet? - Number of cells? - Number of turns? - RF: possibility of using FINEMET? • Need 6D tracking • Need to identify R&D required, especially magnets & RF
