- STFC Cockcroft Review
- Feb 11th 2009
2EMMA
- Worlds first non-scaling FFAG under construction
- 84 magnets, 19 RF cavities. Accelerate electrons
from 10 to 20 MeV in 16 turns - Funded through Basic Technology scheme FP7
Eucard - Being built here.
- On the tour later
3Vision andReality
4EMMA - completion
- Almost halfway through 4 year programme
- Components ordered. Many (magnets, cavities,
vacuum) arrived and being checked out and
preassembled onto girders. - Design of injection/extraction systems
challenging but now complete. - On track to start commissioning November 2009
5EMMA - operations
- Commissioning 12 months (nominal). Much to learn
about new type of accelerator
First proposal by Scott Berg
Additional con?gurations ? Vary time of ?ight
minimum on baseline ? Vary tune ? High
ef?ciency lattice ? Repeat baseline activities,
possibly with different emphases
Baseline con?guration ?Single energy injection
and extraction ? Min and max energy run ?
Lattice tuning ? Map tune and time of ?ight ?
Accelerate single bunch ? Map longitudinal phase
space ? Vary RF parameters and map
longitudinally ? Map transverse phase space
Need to co-exist with ALICE Need to plan / budget
for running EMMA as research machine
6 nsFFAG advantages
- Superior to rapid cycling synchrotron and / or
isochronous cyclotron from some applications - DC magnets cheap, simple
- Very rapid acceleration time
- High currents (frequencyduty cycle)
- Amazingly generous acceptance
- Good dynamic range (factor 4-5 in momentum)
- Round beam pipe, reasonable diameter
- Essential for muon collider/ neutrino factory
7BASROC
- British Accelerator Science Radiation and
Oncology Consortium - Aim hadron therapy in the UK using an nsFFAG
- Members accelerator physicists, medical
physicists, clinicians, industry including many
from Cockcroft and from John Adams Institute,
from Churchill and Clatterbridge hospitals - Arrange meetings, workshops, co-operate in grant
applications
8- First BASROC project, successful application to
Basic Technology schem
9PAMELA
- Design a medical nsFFAG accelerator for hadron
therapy, at the level where it can be proposed to
the NHS/MRC - Pool of people from Oxford, Lancaster, Cockcroft
etc machine designersmagnetsRFclinical input -
10Applications
- Cell dosimetry (Surrey) to validate proton/hadron
deposition as method for killing tumour cells - Next generation dedicated muon source for µSR
(Huddersfield, at Cockcroft) - ADSRs
11ADSRs
- Energy Amplifier (and similar) concept has been
around a long time why no progress? - Accelerator is weak point 10 mA at 1 GeV with
very high reliability - nsFFAG could be the answer simple(reliable),
high current, relativistic energy
12ThorEA
- Workshops on FFAG/ADSR were popular ADSR08
followed on from FFAG08 at Manchester. - Evolved into ThorEA research association more
workshops and co-operative grant bids.

13Where next
- After EMMA next step is proton machine (to
include variable RF frequency) - Energy? Current? Cost?
- Research machine or prototype? Clinical or ADSR
or ? - Where? Daresbury? Harwell? Somewhere else?
- We now need to address these questions.
