Hurh RaDIATE JulyMeeting

4. RaDIATE News Not too early to begin planning for next year’s collaboration meeting! –Volunteer host needed –Set available dates? 4P. Hurh RaDIATE JulyMeeting

5. BLIP Irradiation Run Plan Fermilab conducting an irradiation run at BLIP in FY16/17 and will be paying the associated costs (not insignificant) Include materials from RaDIATE participants that are of interest to Fermilab’s program and/or of general interest to the RaDIATE community RaDIATE participants will have to: –Provide their own samples, including any experiment design labor –Arrange for their own PIE activities Coordination of the irradiation run and simulations of the entire test assembly will be provided by Fermilab and BNL P. Hurh RaDIATE JulyMeeting5

6. BLIP Irradiation Run Plan Several RaDIATE participants can provide PIE services –Perhaps arrangements can be made to cost-share or otherwise minimize PIE costs –e.g. One could consider doing the PIE on BLIP irradiated samples as a separate study using other funding agencies, such as the NSUF in the US or the ESPRC in the UK Regardless of which participant provides what, the results will be shared with all. So, even if you feel that you cannot or will not participate by putting actual samples into the irradiation test matrix, we want to encourage you to participate in: –planning the experiment (setting objectives and priorities) –helping with results analysis –or just giving (good) advice P. Hurh RaDIATE JulyMeeting6

17. Other BLIP Important Parameters No ability for on-line instrumentation –Fear is that signal wires will tangle in sample “cage” conveyor system (see below) –Irradiation temperature designed into cooling “path” via simulation –Simulation-predicted temperature validation via annealing effect Target sample “cages” are irradiated in a 30 ft water “well” and a conveyor system carries the “cages” up and down –Water provides shielding and cooling –Water is recirculated, flowing from bottom to top –Water flows through “cages” and sample surfaces –Samples can be packaged in sealed capsules (welded SS) under vacuum –Thermal path can be designed into capsule to attain desired average temperatures Pulsed beam (6.67 Hz, 440 micro-sec pulse length) P.

19. Next Steps Expression of interest! –Input spreadsheet distributed –Please input on that spreadsheet for specific objectives –Also, can e-mail Pat After we have input, we will combine on one spreadsheet –Distribute compiled table –Ask for interest on individual studies from other participants Combine studies to make more efficient (reduce total number of samples) Perform simulations to judge energy degradation limits Remove scope to fit within 201 MeV limit P.
