Roger Barlow: FFAG developments

Slide 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



Slide 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 1st April 2007



Slide 4

3 Components

• EMMA: Construction of the first NS FFAG to prove the principle, and study behaviour. £5.3m over 3.5 year project lifecycle (Equipment £3.8m, Staff £1.5m)

• PAMELA: Design of a hadron therapy machine funding - £865k

• Applications: exploitation of other areas where an FFAG could be used funding - £273k

EMMA summary

Final Design Review Daresbury 10-11 Dec

Main components on site by 1st Aug 08

Assembly on girders June 08-Jan 09

Assembly in hall Jan -May 09

Installation and testing Jun-Aug 09

Operation in September 09



Slide 13

PAMELA

• Clinical Hadron Therapy machine, probably at Oxford

• Carbon is essential. Proton solution is commercially available.

• 3-ring solution (Keil and Trbojevic) or 1 ring (Koscielniak and Johnstone)

• Workshop next summer to settle final parameters



Slide 14

Applications

• Cell Irradiation – Surrey post filled. Answer questions about dosage, Ion types, etc

• ADSRs – Manchester+Leeds. Additional grant obtained to look at energy possibilities.

• Neutrons: Leeds post now being advertised



Slide 15

Future

• ADSR workshop here January 7/8

• EMMA construction and commissioning 2008 on

• FFAG2008 workshop in Manchester, September

• Working nsFFAG at Daresbury in September 2009
