Box S Mounting Platform Shipping Unit Box S - Mounting Platform • Completed Arde (07/2005) Martina Green
Open Issues with Flight Module • Vessels heaters • Foil or stick: waiting for Arde’s feedback • Installation: Arde or MIT • Thermostats: to be finalized & ordered • TRD heaters: Power? (UB’s details) • Xe/CO2 vessesl: Fill Location & Procedure • Arde Contract: Subcontract? Martina Green
Box S EM - Previous Status • Passed vibration test at ENSA(12/2003) • Reduced 1st Buffer Vol. (10/2004) CO2:15 5 c.c.Xe: 30 15 c.c. • Box S + Box C MIT:cabling/manual tests (11/04) • D-Vessel: added a ss tube w/1-mm holes(11/2004) Martina Green
S.S. Tube: with 1 mm holes Mixing Vessel Modification Martina Green
Progress of Box S – EM at MIT • Portable clean room:perform manual tests • Ardé visited MIT:(02/2005) • Visits ofINFN-Rome & A. Lebedev @ MIT(03/2005) • updated w/ flight module USCM (Lebedev) • new gas mixing software (Rome & Lebedev) • tested & evaluated software • CO2 & Xe transfers tests: validate buffer volume Martina Green
