Title: EMMA, BASROC, Hadron Therapy and ADSRs


1
EMMA, BASROC,Hadron Therapy and ADSRs
  • Roger Barlow
  • STFC Cockcroft Review
  • Feb 11th 2009

2
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.
    www.thorea.org
  • Mix of institutes and disciplines, research and
    industry
  • Grants from
  • EPSRC LeedsManchester
  • EPSRC Cambridge
  • STFC PNPAS ManchesterHuddersfield

13
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.
