  1. iPASI CollaborationHigh Power Targets RaDIATE Collaboration UK-PASI programme 3. Collaborative activities between Fermilab/STFC Chris Densham & Patrick Hurh Targets Working Group Co-conveners

  2. 1.iPASI: RaDIATE Collaboration (as I understand it) iPASI (international) participants in RaDIATE and other PASI related Target Activities RaDIATE Collaboration (named on draft MoU) PASI-UK International Fermilab Brookhaven NL Pacific Northwest NL Oak Ridge NL Argonne NL Los Alamos NL FRIB/MSU CERN ESS (?) STFC/RAL ISIS High Power Targets Group Particle Physics Dept ASTeC UK materials community Oxford (MFFP Group) Manchester National Nuclear Lab Baznutec Ltd PASI-UK Universities Sheffield Warwick Huddersfield

  3. New collaboration set up after 1st PASI workshop (Proton Accelerators for Science & Innovation) at Fermilab, January 2012 http://www-radiate.fnal.gov/index.html MoU between Fermilab, BNL, Pacific Northwest NL, STFC, University of Oxford - just signed by DoE! More details in Kavin Ammigan and Barry Jones talk in WG1 Session 2

  4. RaDIATE Objectives • As proton accelerator particle sources (target facilities) become increasingly powerful, there is a pressing need to better understand and predict the radiation response of structural window and target materials. • RaDIATE aims: • Introduce materials scientists with expertise in radiation damage to accelerator targets community • recruit and develop new scientific and engineering experts who can cross the boundaries between these communities • Generate new and useful materials data for application within the accelerator and fission/fusion communities; • co-ordinate in-beam experiments and post-irradiation examination • Initiate, coordinate and exploit a continuing synergy between research in these currently disparate communities

  5. Parameter space for consideration by Oxford RaDIATE materials programme

  6. RaDIATE news • Monthly meetings (5 so far) • DPA calculation incorporation into MARS • Necessary for all material studies • Scoping study underway by NNL/Oxford (c/o Steve Roberts/Materials for Fission & Fusion Power Group) • Initial report on Beryllium on website (Colin English/Barry Jones/NNL) • Graphite report underway (Graham Hall/Manchester) • ‘PASI’ Post-doc recruitment at Oxford awaiting full funding • To work on beryllium & beryllium alloys • Widely applicable for beam windows and low-Z targets • Interesting new research topic

  7. RaDIATE news (continued) • Graphite in-beam tests at BLIP/BNL • University of Manchester now part of URA • NNUF (National Nuclear User’s Facility) at Culham(Real news!) • To perform activated materials testing (micro-mechanical) • £5M equipment purchase underway • £10M earmarked next year • Hope to include tungsten research in future (seek funding by ESS?) • Testing of unirradiated samples of ISIS tungsten targets at Oxford (MFFP) underway • Collaboration underway with SCK-CEN (Belgium) to perform materials tests on irradiated ISIS tungsten target • Samples would be passed to NNUF for micro-mechanical tests

  8. 4mm 3mm 10mm 3mm 1um Micro-mechanical testing • Unique materials expertise at Oxford (MFFP Group) • Micro-cantilevers machined by Focused Ion Beams • Compression tests • Tension tests • Three Point Bend • Cantilever bending

  9. 2. PASI-UK Programme (co-ordinator Rob Edgecock) • WP1 – ‘Generic’ tools for high power target development and operation (c/o David Jenkins) • Task 1: Monitoring systems – structural, heat transfer, erosion/corrosion integrity + temperature • Task 2: Studies for high Z targets • WP2 – ISIS upgrades (c/o Matt Fletcher) • Task 1: Improvements to TS1 target (up to 0.5 MW) • Task 2: ESS contributions • WP3 – Fluidised tungsten (c/o Chris Densham) • Flow rig development • Pulsed proton beam test at HiRadMat facility • All topics covered in more detail in WG1 Session 3

  14. PASI-UK: generic (tungsten) test equipment in preparation Jet diameter < 10mm Water velocity: 1-50m/s Tantalum coated tungsten sample • High pressure water erosion test rig – components delivered (Tristan Davenne/Otto Caretta) • 10 kW, 400 kHz induction heater power supply delivered e.g. for Mu2e or ISIS target testing (Tristan Davenne) Impinging water jet UV steriliser nozzle Steady-State Von-Mises Stress Field Chilled water circuit Water flow meter Tension Buffer tank Pump Thermostatic control valve filter Compression PSU purchased for high temperature tungsten fatigue (Peter Loveridge, Roger Bennett, Ali Ahmad)

  15. PASI-UK WP3: Fluidised tungsten powder technology • Potential solution for applications requiring highest pulsed beam powers e.g. Neutrino Factory • New technology demonstrated off-line at RAL • In-beam experiment on powder sample carried out at CERN • First experiment to be carried out at new HiRadMat test facility in May 2012 • Collaboration with Ilias Efthymiopoulos,Nikolaos Charitonidis (CERN) • 2nd experiment planned after long LHC shutdown
