Irradiation to be completed during next runSlide4
BLIP Irradiation Update

Raster beam profile
Inner sweep radius (0.55 cm) and beam sigma (0.51 cm) unchanged
Outer sweep radius changed from 1.5 cm to 1.2 cm
Higher peak fluence, but reduced flat profile area
DPA calculations need to be updated
Inner sweep: 0.55 cm, outer sweep: 1.5 cm
Inner sweep: 0.55 cm,
outer sweep: 1.2 cmSlide5
BLIP Irradiation Update
Target box is currently cooling down in the BLIP hot cell
Measured dose rate was much lower than calculationsSi, High-Z and DS Ti
capsules will be shipped to PNNL for PIE work
RaDIATE
BLIP run is expected to resume early next year
BLIP operation scheduled to start first week of January 2018Expect higher irradiation cost because of no cost-sharing with RHIC operationRHIC not scheduled to run with protons until March 2018

Next Steps
5 more weeks of irradiation in 2018 (total of 8 weeks)
BLIP to restart the first week of 2018Schedule RaDIATE
irradiation as early as possible in order for specimens to be available for
HiRadMat
experiment later in 2018
Need to decide on new materials/capsules very soon!! To replace either/both Silicon (5.6 mm) or/and DS-Ti/High-Z (2.2 mm) capsule slots (about up to 14 MeV available)
FLUKA analysis and safety document need to be updatedPotentially high dose rates at end of irradiation if higher Z materials are addedReview by BNL BLIP safety committeeDesign and fabrication of specimens, new capsules, capsule holders and vacuum degraders will take time!

Next Steps
Shipment and PIE of Si, DS
Ti
& High-Z capsules
Currently planning to split shipments to meet Type A shipment requirements
Si & DS
Ti
capsules in first shipmentHigh-Z capsule in second shipment, after longer cool-downNeed to start arrangement for shipmentCapsule loading, packaging, paperwork, etc.Mike Clancy the contact person at BNL?
PIE work arrangements between institutions and PNNL
Set up contract with PNNL for PIE work
