RaDIATE News

• MOU Status– Revision signed and master copy distributed– Planning another revision to add new participants during

CY 2016

• HiRadMat “BeGrid” experiment status– Beam time starting Sept 14– Rig is being fabricated at RAL, will be tight to make scheduled

delivery to CERN on August 24

• NSUF Users Meeting (Nuclear Science User Facilities)– Kavin and Pat attended– Met with D. Senor (PNNL), R. Kennedy (INL) and J. Cole (INL)

to discuss using NSUF partner facilities for Target R&D• In a nut-shell: Make the objectives relevant to Fission, don’t

mention accelerators

RaDIATE News

• Not too early to begin planning for next year’s collaboration meeting!– Volunteer host needed– Set available dates?


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


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

Facilities CURRENTLY Integrated and in UseBLIP (Brookhaven Linear Isotope Producer)

Tandem Van de Graaff: Irradiations with 28 MeV protons (197Au ion irrad planned)

Isotope Extraction-Processing Facility: An experimental area in the facility hot cells for complete macroscopic analysis of irradiated samples

Center of Functional Nanomaterials: A complete experimental evaluation (electron microscopy, EDS, annealing, DSC/TGA, etc.) of un-irradiated samples for base lining

BNL Light Sources NSLS (X17B1 and X17A Beamlines) – beamlines used to-date for x-ray diffraction

BLIP or Tandem irradiated reactor and/or accelerator materialsNSLS II (XPD Beamline) – Beamline used for Glidcop benchmarking during

commissioning

Neutron Energy Spectrum

Experimental Facility occupies 2 hot cells and a HEPA-filtered fume hood

PIE analyses performed are:

PLUSPhoton spectra and isotopic analysisActivity measurementsWeight loss or gain

Macroscopic Post-Irradiation- Isotope Extraction and Processing Facility



Center of Functional Nanomaterials (Paola Nocera will expand on this)

Complimentary post-irradiation experimental activity(a) Electron Microscopy (SEM & TEM)(b) Annealing Studies under various atmospheres (vacuum, air, oxygen and noble gases) (c) Differential Scanning Calorimetry and TGA(d) Dual Beam and TEM


Synchrotron Experiments Conducted to-date

Multi-functional stage capable of handlingReal size irradiated specimens, under vacuum and four point bending state of stress and eventually Heating/annealing via a portable, collimated laser beamTensile stress-strain test



BNL Post-Irradiation Facilities X-ray Diffraction at NSLS & NSLS II

X-ray diffraction studies of irradiated samples with the aid of a multi-functional experimental stage enabling:• Laser-induced annealing• Tension/twisting/4-point-bending• Exposure to different environments• Diamond anvil cell to be introduced in future update

Stage at NSLS II XPD Beamline

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)


18

Discussion of BLIP irradiation environment

• Open for questions


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
