Accelerator Technology
Accelerators are everywhere. Many different uses. Many different communities.
NS-FFAG advantages • Cheap, simple DC magnets. • Compact design • High repetition rate and duty cycle• Rapid acceleration• High acceptance• Permanent magnets (?)• Continuous operation (?)
‘Cyclotron currents at Synchrotron energies’
CONFORM
Construction of a Nonscaling FFAG for Oncology, Research and Medicine
Build EMMA: 20 MeV electron prototype to demonstrate principle
Design PAMELA: clinical machine for hadron therapy
Investigate other applications
The Bid
Bid to Basic Technology fund
Successful and fully funded £6.9M awarded
£5.5M to build EMMA
Posts to design PAMELA
Posts to identify and develop applications
Administrator
Start 1st April (?)2007 for 3½ years
EMMA
Design already complete last year
Since then: magnets realigned, magnet shims added, fewer RF cavities
Magnet prototypes now ordered (almost?)
Injection and extraction seem possible
EMMA
• Team in place• Strong co-operation
from Daresbury• Regular meetings run
by Rob and Neil
• Design still changing• Hard to establish
baseline• Reliance on outside
expertise • Will it work?
PAMELA
Long wish-listBuilders and
users (medical community) in discussions about how to achieve all of these
Prove proton NSFFAG works
Provide ~40 MeV protons for cell studies
Provide ~300 MeV protons for therapy
Provide ~40 MeV/N He and C for cell studies
Provide ~450 MeV/N He and C for therapy
PAMELA
Multi-stage design (2+1 rings, or ovals)
Injector and injection energy not clear:
18 MeV Cyclotron off the shelf – but only for protons
4 MeV RFQ neater – but harder
p (MeV/c)
E (MeV)
87 4
184 18
274 40

750 300
ApplicationsIdentified
• Hadron Therapy: parameters for PAMELA
• Cell irradiation studies• Muon sources• Neutron sources• Neutrino factory• ADSR thorium reactorsOthers?
