Discussion topics:
* tomorrow (Tuesday 5) a technician will come to replace the pump in
the primary cooler. Krista will need Wednesday to connect it to the
CO2 system again. She hope we'll be up and running on Thursday
afternoon.
* When doing the He leak test of N023 Krista noticed that the VCR
thread was not good. It really needs a wrench to close it. It ewas
leak tight, but she wonders if this is a problem for Liverpool. We'll
bring it up in the module-0 meeting tomorrow. Robbert didn't notice
anything on previous modules.
* glue beading:
* Wouter is to send the DCB test pieces to Jan
* Wouter asks about cleaning the ASICs. We don't do it, but Krista
reminds us that both in Manchester and at Nikhef it was found to
make no difference.
* Wouter will clean a few ASICs in the plasma cleaner. We can then
deposit glue on these to see if that's any different than without
plasma cleaning.
* Krista has problems with the gitlab repo again. Her modifications do
not end up in the main branch. Will ask Aleksandra to help.
* Wouter or Igor still needs tofinish the hybrid gluing script
* Krista would like to go through the Jira task list in the
meeting. There are still many open items.
* electrical tests:
* just before the vacation we have tested module 18. We had problems
with links and got a high bit error rate.
* Daniel has suggested that we redo the electrical tests of all
modules. The short term plan is to start with module 19, which has
not been tested at all yet. We will do the full set of tests,
including the temperature cycling.
* Modules N020 and N022 still need HV cables before they can be
wire-bonded. Krista can do this. Wouter will plasma clean the cables
before Wednesday.
* Before we decide to use jig B:
* Wouter will measure N007, NRD4 and N022 another time with jig B
* We will ask Martijn to measure N022, or another 'finished'
module.
* Krista still needs to adjust the magnetic mounts on jigB as one
of the transfer jigs doesn't fit right now.
Planning:

Tuesday 19th. Available by remote connection.
