Present: Thiziri, Paul, Bhuvan, David, Karim, Cyrille, Francesco, Thibaud, Stephanie, Pascal, Reina

 

General news:

• new version of module-qc-tools
• Task force on the Core column? Not clear the formality of this effort, we will start (.. continue) to investigate
• Inventory 29/04-03/05

Parylene

• Module 6: tab broken. Contnue with masking? We decided to try
• 7 masked + PPP6
• PPP40 is done but useful for core column
• PPP41 done but tests to be checked
• PPP42 to be tested, candidate for further parylene
• Foam pillars for the module cover are arriving this week

Wirebonding:

• PPP50 needed to re-place most of the wires, ready to be bonded
• PPP38 and PPP39 in the pipeline
• Oxided ultrasonic screws -> needed to change parameters to much higher. We have ~50 screws like that
• We found 2 screws from another lot that are good

Testing:

• PPP40 completely tested
• PPP41 completed INITIAL/WARM without errors (software/measurement); 3x FE with normal results but 1x FE with strange (bad) results. To be checked with experts
• PPP42 is ready to be tested
• PPP37 is wirebonded, DB data is to be checked. Missing photo (?)
• We need to proceed for the SQ slides
• We need to investigate the grounding loop on the CAEN

Outer barrel wirebond protection

• 3 glass tests done. Measuring glue thickness. 
• Vacuum issue: a lot of leakage
• Step 0 done
• Step 1 (glass) ongoing for the SQ

Metrology:

• Bare Module
  • Review state of the measurements and upload to PDB
  • The IVs have been done but not uploaded
• Flex
  • Same situation as BM
• Assembled module
  • Carrier to be added to PPP50

Gluing:

• Nothing to report
