LHCb thermal tests
No vacuum chamber available
TRACI in 187
We need a heater..
Thin SS foils
Re-usable bloc
Pelletier
Small resistors on Cu plate
IBL Kapton foils custom foils (20 x 20 mm)
Use theirs or order more?
IBL Silicon dummies with silver film, one Pt-100 and wires soldered (20 x 40 mm)
Silicon thermal mock-ups with Simone Traverso !! (meeting with Jan, Andrei asap)
Who should prepare the devices for testing
Nanoports and interface with Swagelok connectors and SS capillaries (Jerome Noel)
Heater with thermal paste on top of cooling plate (who does it??)

5. NA62 Dual Inlet wafer SOI-353
Channels and manifolds have been etched
After stripping the hard masks (SiO2, SiN), the surface was contaminated

In the coming days
Tuesday: RCA cleaning + bonding
Litho Pool #2
Etching Hard mask Pool #2
Litho Inlets
Etching Inlets
KOH etching pools
Dicing latest end of next week…
Connectors
Hydraulic test w/out and w/ vacuum
Then we should decide which heater we should use..
Ceramics thermal mock-ups
Thermal mock-ups from Aurélie Pezous could be delivered when?
Integration to PCB could be done with both

ALICE
Testing could start at the end of winter shutdown (14th of march)
Which plant should we use?
DSF cooling plant will be tested for an SPD spare sector which should be commissioned for the next shutdown
2 loops are available and only one is needed by SPD… to be discussed with them.
Crystal Palace cooling plant
Modifications required (2 hrs) + testing of the plant (1 day)
Andrea Francescon
will do the modifications next week
Will start working on the microfabrication asap (next monday pm?)
