5. Target Crucible Material: hBN Custom pliers to handle hBN crucible
Hexagonal Boron Nitride
Custom pliers to handle hBN crucible
Gallium does not ‘wet’ to hBN
No metal contaminates

6. Radiator/Target Assembly (1/3)
Air cylinders to position target, provide solid contact to LCW cooled copper plates

7. Radiator/Target Assembly (2/3)
Quick connects on LCW for ALARA
Enable rapid disconnection for ’cooldown’

8. Beryllium Window Expected temperature rise
Electron beam welded .015 inches thick PF-60/ 99.0% min., Beryllium window to a 04.5 inch aluminum single-sided conflat flange over a 02.5 inch aperture. Pressure tested to 1.5 atmospheres
From Hall C, PR #195038
Expected temperature rise
0.8 GPM 60 PSI drop
1 kwatt load; 4.7˚C rise
Vacuum system tied into Fast valve

9. Instrumentation 1/2
An addition set of electron beam diagnostics will be added and cross calibrated to 4D00 dump line diagnostics
BPM
Harp
Beam Viewer
Two additional video cameras will be monitor irradiation of Gallium
One for position of beam on radiator – or BPM?
Second is to give overview in case something goes wrong

10. Instrumentation 2/2
Radiation sensitive detector & camera to monitor beam position on radiator
3 Thermocouples to monitor critical temperatures
All monitored in EPICS w/alarm
#1 Tungsten Radiator
#2 Boron Nitride target holder
#3 LCW outlet
LCW return water flow switch

11. Risks & Hazards
Sealed raised edge on copper plate to prevent spillage in the event of hBN crucible failure
Cover fitted to top of hBN crucible
Long fitted pliers to remove hBN crucible
Extended handle for ALARA
Quick connections on water cooling lines for ALARA
Temperature monitoring to prevent overheating
