BLIP Experiment Update
BNL UpdateSafety committee reviewFLUKA activity results
Capsule holder & vacuum degrader designs and fabricationBLIP operations updateExperiment start date: Feb. 27th
?
Capsule & target drive assembly?

Capsule update
Ti Capsules (FRIB, KEK, FNAL, Oxford/RAL)Meso-scale fatigue foils (RAL)
Si/High-Z Capsules (CERN, KEK)Al Capsule (ESS)Be/C Capsules (FNAL)

Current issues
ESS Al capsule distortionCenter of capsule bulged out by about 2.5 mmFiller specimens slipped out of
position during transport?Possible reasonsPressure differential during cargo transport?Leak checking in vacuum?
Latest update from
Yongjoong
Spare back-up capsule at ESS has a max. deformation of 0.3 mm
To be clamped between rigid plates and placed in air-tight rigid box prior to shipment to BNLFNAL considering partial fill if Be and
Ti
capsules for external pressure differential to keep specimens clamped in place
Not an issue for vacuum capsules
K. Ammigan – January, 2017
5Slide6
Current issuesPossible late delivery of FRIB
Ti specimensBack-up is to replace 1 mm FRIB layer with KEK fatigue specimens
Non-uniform energy degradation due to gaps in meso-scale fatigue foil acceptable?K. Ammigan – January, 2017
6Slide7
Next steps
Actions to fix Al capsule and back-up planUse spare capsule at ESS, and clamp during transport to BNL
Use spare DS Ti capsule to weld at EB industries?Plan travel for Be/C/Ti capsules assembly and welding at BNL
Schedule welding at EB industries
Feb. 6
th week?
Capsule/specimen activity results?Delivery of all capsules to BNL in early February
Post-irradiation specimen transport
Need to identify Type A container (new, re-certify, rent?)
