Thursday December 02, 2021, 3:00pm Bluejeans https://bluejeans.com/465620466
- Present - Elton, Dave, Stephanie, Ilya, Rory, Mark S, Beni, Simon, Mark I
Agenda
- Minutes from last meeting https://halldweb.jlab.org/wiki/index.php/November_18,_2021_CPP_Design_Meeting
- Beam extend till December 21 - this will delay start of installation but we should be fine
- Testing status - Beni/Elton
- Design/Fab/Procurement status
- Lead absorbers - Due in next week
- All assembly hardware either here or due in by December
- Test install in the TEDF High bay - use of 2 or 3 chambers
- Installation/assy 3D Model and dwgs
- LV attach
- Scintillator orientation
- assembly components - drawings released
- Installation drawings in final review
- Lead Target flattening media:Lead_target_pressing.pdf
- Target Design in work
- Most parts made (a good portion are 3D printed)
- Will do a test assy by the end of the month
- Things to work out
- Gas system, manifold/bubblers (Beni has some)
- Complete structural analysis - approved by Tom Renzo - need to release into system
- Develop Detailed installation plan
- Develop Design/operational/Maintenance Requirements
- Modified US vacuum system
- Solid target installation
- Installation drawing including Microscope move
- CPP Detector operations in Hall D OSP
- Possible use of nitrogen flow for cooling electronics in Faraday cage
Minutes
- Elton met with nick and discussed LV box. Need to make bracket smaller (1/16" thick) boxes should be on top-north corner of each chamber
- For fiducializing chambers, all four edges or bolt holes can be used to find center. Machining is very accurate
- Proposed chamber orientation good - horizontal x-ray port DS, Vertical x-ray port US
- Rory/Elton requested 4 scintillator paddles, 2 BL and 2 BR in vertical position equally spaced (15" oc). To be held by light guides, maybe a V block
- Lead Target needs to be pressed flat since it is malleable and has the center protruding
Action Items
- Stephanie to design thinner "L" bracket for the LV box
- Tim - Get with S&A group to discuss chamber fiducialization and alignment
- Rory to flatten lead target
- Stephanie to model and place scintillators and attachments
- Release installation drawings - Tim/Stephanie
- continue work on target installation - Bobby
