EMMA, BASROC,Hadron Therapy and ADSRs

• Roger Barlow
• STFC Cockcroft Review
• Feb 11th 2009

EMMA

• 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

EMMA - 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

5
EMMA - 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

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

7
BASROC

• 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

9
PAMELA

• 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

10
Applications

• 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

11
ADSRs

• 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

12
ThorEA

• 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.

• Mix of institutes and disciplines, research and
  industry
• Grants from
• EPSRC LeedsManchester
• EPSRC Cambridge
• STFC PNPAS ManchesterHuddersfield

Where 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.
