RaDIATE Meeting February /20/13P. Hurh RaDIATE February 2013 Meeting 1

Agenda RaDIATE News (MOU status, Postdoc recruitment status, NNUF, etc.) Status Updates Stage 1 on Be Stage 1 on Graphite DPA and gas production modeling BLIP graphite progress Interim Report(?) MARS modeling of lower energy ion beam on low-Z materials (compare to high energy proton?) Post-Doc Material of Study Choice 2/20/13P. Hurh RaDIATE February 2013 Meeting 2

RaDIATE News MOU No additional news since January mtg Post-doc recruitment Decision to start recruitment activities soon Possible post-doc candidates available in Fall Project X Energy Station Workshop Interesting talk on Comparability of Proton to Neutron irradiation (more later) University of Manchester now part of URA NNUF is spending money! PSI STIP information being added to RaDIATE web-site 2/20/13P. Hurh RaDIATE February 2013 Meeting 3

Status Reports Be literature study (anything new to report from Barry Jones or Colin English?) Graphite literature study (just bringing Manchester group up to speed) Modeling (sorting out DPA and gas production estimates) BLIP status (next trip dates?) Reminder: Interim report due end of Feb. Final report due end of May/beginning of June 2/20/13P. Hurh RaDIATE February 2013 Meeting 4

White Board and IMT Tables Stage 1 teams need to decide in the next few months whether we can work with the materials we have or whether we will need new irradiations 2/20/13P. Hurh RaDIATE February 2013 Meeting 5

Damage profile comparison What is the energy of the many ion beam accelerator facilities? How does the damage and gas production compare to that of high energy protons? Can we utilize these facilities for efficient irradiations of materials? For Be, can use micro-mechanics? How do measurements on the micro scale tell us bulk properties? 2/20/13P.

Practical Pros/Cons 2/20/13P. Hurh RaDIATE February 2013 Meeting 9

Post-Doc Material of Study Choice Beryllium seems to be most interesting because: LBNE paying for major portion of Post-Doc costs so Low-Z neutrino target mat’l is probably a good idea! Broad application since all High Intensity Machines will need Be windows (probably) Research programs on graphite and tungsten (for nuclear applications) are already being done Graphite work (for acc. applications) is ongoing at BLIP and will continue there (possibly elsewhere) under RaDIATE Tungsten work (for accelerator applications) can probably be done by STFC under RaDIATE (Oxford studentship?) Structural radiation damage work on Beryllium is not happening anywhere and will not get done by another program anytime soon Some experience with Be from fusion research at Culham 2/20/13P. Hurh RaDIATE February 2013 Meeting 10

Action Item List from January Arrange phone meeting with S. Roberts to discuss recruitment decision (Hurh/Densham) Send Be information to Barry Jones and Colin English (All) Contact Manchester team for progress report at next mtg (Densham/Roberts) Contact PSI on STIP sample use (Hurh/Densham) Continue work on modeling prototypic gas production cases that we can then scale from (Mokhov, Hartsell) 2/20/13P. Hurh RaDIATE February 2013 Meeting 11

Action Item List from January Continue work to prepare for tensile testing at BLIP (Ammigan, Simos) Investigate further availability of irradiated materials for testing (esp Be at CERN and AP-0) (Hurh/Ammigan) Continue work on Be lit study, graphite lit studies and W studies? (All) Arrange for February Meeting (Hurh/Ammigan) 2/20/13P. Hurh RaDIATE February 2013 Meeting 12

Next Meeting End of February? 2/20/13P. Hurh RaDIATE February 2013 Meeting 13
