LHCb-1 #6918 inlets before dicing 3/5/12 Alessandro Mapelli - µcool weekly - CERN

Alessandro Mapelli - µcool weekly - CERN 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??) 3/5/12 Alessandro Mapelli - µcool weekly - CERN

NA62 Dual Inlet wafer SOI-353 Channels and manifolds have been etched After stripping the hard masks (SiO2, SiN), the surface was contaminated 3/5/12 Alessandro Mapelli - µcool weekly - CERN

NA62 Dual Inlet wafer SOI-353 Contamination seems to be passivation polymers from DRIE.. 3/5/12 Alessandro Mapelli - µcool weekly - CERN

Alessandro Mapelli - µcool weekly - CERN 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 3/5/12 Alessandro Mapelli - µcool weekly - CERN

Alessandro Mapelli - µcool weekly - CERN 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?) 3/5/12 Alessandro Mapelli - µcool weekly - CERN
