Meeting Agenda

BLIP experiment update (BNL)Capsule and specimens fabrication/assembly updatesTi (FRIB, KEK, RAL/Oxford, FNAL

)Si/High-Z (CERN, KEK)Al (ESS)Be/C (FNAL)

Current

issues (Al capsule distortion,…)

Next step and schedule

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?

K. Ammigan – January, 2017

3Slide4

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)

K. Ammigan – January, 2017

4Slide5

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?)
