EMMA/BASROC/CONFORM etc: FFAG developments at the Cockcroft Institute Cockcroft SAC - 26 November 2007 Roger Barlow

Cockcroft SAC 26 November 2007 Roger Barlow: FFAG developmentsSlide 2 BASROC British Accelerator Science Radiation Oncology Consortium An association of universities and institutes (Cockcroft and Adams!). Group came together out of PPARC meeting aimed at raising accelerator activity outside particle physics Aim to build a complete hadron therapy facility using an NS-FFAG. Hope to increase use of accelerators, their manufacture, R and D etc in the UK General umbrella for CONFORM and other projects, e.g. Medical Instrumentation Meeting

Cockcroft SAC 26 November 2007 Roger Barlow: FFAG developmentsSlide 3 CONFORM Construction Of a Nonscaling FFAG for Oncology, Research and Medicine Project (first of many?) produced by BASROC Successful bid last year to Basic Technology fund for £ 8M Outline proposal put together – selected for consideration Full proposal written across many institutes and submitted through Manchester. Interviewed by panel. Funded in full – announcement 12 months ago Started 1 st April 2007
