Dear all,
Here are some minutes for our meeting on 03/09/2009.
Please let me know if there are errors or omissions...
Regards, Daniel.

http://ilcagenda.linearcollider.org/conferenceDisplay.py?confId=4154
Marc:
* 1 full-size alveolar layer built
* assembly mould being designed, ready end october
* tool for core removal being developed
* change to "U" structure possible (cost of 2 months + 3keuro)
"H" structure is still baseline
* curing of large assembled structure still needs study
Denis:
* recent results on demonstrator studies will be uploaded by Julien tomorrow
* studies of convection
* studies of thermal foams & gels
* heat pipe system should be available by end september
* monoblock cooling system for 90 degree geometry prepared
- will need to adapted for 45 degree geometry
* discussion of mechanical support for "H"s in structure (for 90 degree case). 2 poss: support H structure at edge or the PCBs at the centre.
- need to consider 45 degree case
!!!!!!!!!!!!!!!!!!!!!!!!!
n.b. for shape of instrumented region of EUDET, the baseline is for a 45 degree tower some distance inside the structure (~15-20cm from edge).
One long slab is also forseen (probably not completely instrumented, but with a few functional ASUs at each end and in the centre).
!!!!!!!!!!!!!!!!!!!!!!!!!
Patrick:
* work on equipment for soldering 18cm boards
* new kapton cables received for tests
Maurice:
* working on controller for heater lamp
* PCBs have arrived, they are being equipped
* firmware development will take ~2 weeks
!!!!!!!!!!!!!!!!!!!!!!!!!!
Patrick and Maurice should keep in close contact to prevent overlaps/inconsistencies. Perhaps Maurice can come to Paris for a few days in the next month or so.
!!!!!!!!!!!!!!!!!!!!!!!!!!
Remi:
* FEV7 COB (chip on board) PCB prototype has arrived.
- will test bonding of chip
- next version being prepared by Stephane (with extra Cu layer on top)
* DIF firmware has been developed by stagaires over the summer
- allows some slow control commands etc
- is being cleaned up by Remi
- will allow first tests of FEV7+SPIROC2 when available
* HV kapton gluing tests started with Patrick.
Roman:
* presented prelim agenda for Lyon meeting
* think about possibilities for trans-national access. This is an essential part of the EUDET project: our "infrastructure" must be utilised by international EU partners. Perhaps it could be used for cooling tests together with CERN?
There are minutes attached to this event.
Show them.
