  1. LHCb Alessandro Mapelli - µcool weekly - CERN

  2. LHCb-1 #6918 inlets before dicing Alessandro Mapelli - µcool weekly - CERN

  3. 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??) Alessandro Mapelli - µcool weekly - CERN

  4. NA62 Alessandro Mapelli - µcool weekly - CERN

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

  6. NA62 Dual Inlet wafer SOI-353 • Contamination seems to be passivation polymers from DRIE.. Alessandro Mapelli - µcool weekly - CERN

  7. 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 AuréliePezous could be delivered when? • Integration to PCB could be done with both Alessandro Mapelli - µcool weekly - CERN

  8. DRIE http://www.iue.tuwien.ac.at/phd/ertl/node68.html Alessandro Mapelli - µcool weekly - CERN

  9. ALICE Alessandro Mapelli - µcool weekly - CERN

  10. 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 microfabricationasap(next monday pm?)
