Presentation Transcript

  1. Accelerator R&D • FFAGs........EMMA, PAMELA, ADSR, etc • Target studies.........neutrons for BNCT, ADSR, security, etc

  2. NS FFAGs • Non-Scaling Fixed Field Alternating Gradient • Invented for muon acceleration in a Neutrino Factory Also interesting for other applications. For example: hadron therapy ADSR Proton acceleration

  3. NS FFAGs • But.....novel features.......must build PoP machine • Not cheap, so where does the funding come from? • Exploit KE possibilities, via BT fund • CONFORM consortium: £8.2M • Build PoP machine – EMMA • Design Hadron therapy machine – PAMELA • Study other applications, mainly ADSR and muons • Started 1st April 2007, finish March 2011.

  4. EMMA

  5. EMMA Status • Being commissioned • Beam has made many turns at fixed energy • Acceleration being worked on....will restart in Jan • “2 year” experimental programme to follow, subject to funding EMMA Control room 22:45 on 22nd June 4-sector commissioning

  6. PAMELA

  7. PAMELA Status • Design study finished and being written up • Next step - prototyping: • Ring magnet • RF cavity • Extraction kicker • There is interesting in building it

  8. ADSR

  9. Accelerator • Crucial component • 10MW • well beyond state-of-the-art • 99.9% reliability • unheard of! • needs redundancy • Only two candidates: • linear accelerator ← expensive • FFAG ← build ~3 for same price

  10. Isochronous 250-1000 MeV NS FFAG Ring 2m General Parameters of an initial 0. 250 – 1 GeV non-scaling, isochronous FFAG lattice design Clockwise: Ring tune from design script, deviation from isochronous orbit (%), and radius vs. momentum • Comments and further work • Tracking results indicate ~50-100 mm-mr; relatively insensitive to errors • Low losses :

  11. Target Studies • Most likely show-stopper for a Neutrino Factory • 4MW beam, 0.75MW in target, 300J/cm3Thermal shock: >1GPa – exceeds tensile strength Temperature: 100K/pulse, 50 pulses/s Radiation damage Radiation safety! • Solution found using tungsten • Has involved: • modelling of energy deposition, stress waves, etc • measurements of shock and cf with modelling • simulation of pion, neutron, etc, production • activation studies, shielding requirements • cooling studies

  12. Target Studies Measured Young’s Modulus & yield strength of W and Ta at higher temp and strain rate than anybody else. Expertise gained applicable elsewhere.

  13. BNCT Boron Neutron Capture Therapy • Used, for example, to treat “glio-blastoma multiforme” • Use boron-10: stable, but fissions with a thermal neutron Needs a lot of ns: 1x109 cm-2s-1 for 30mins Only current source: nuclear reactor! Possible with accelerators: 5mA protons at ~2.5MeV  12.5kW in ~100m • Accelerator & BNCT facility exist in Bham • Project to upgrade starting: aim clinical trials

  14. BNCT

  15. Other Target Activities • Thermal neutrons for • ADSR • Waste transmutation • Security applications • Goran Skoro: possible next ISIS target expert
