1. AMS Ground Safety Review II Sept. 2008 – KSC 1 AMS 02 –Thermal Control System Design Thermal control GSE at KSC

2. AMS Ground Safety Review II Sept. 2008 – KSC 2 AMS 02 –Thermal Control System Design TCS – GSE scope AMS at KSC will be in flight configuration (radiators) The TCS GSE shall allow the correct detector operation during the ground integration. The only GSE to be used at KSC will be electrically powered fans of two kind, to provide forced convection cooling. Several fans will blow air towards specific AMS components in order to keep their temperature in the operative range.

3. AMS Ground Safety Review II Sept. 2008 – KSC 3 AMS 02 –Thermal Control System Design Elements to be cooled –Air cooling Electronic crates and XPDs –Main radiators (RAM and WAKE) mounted Cryocoolers (with LHP integrated, hence sunk to the zenith radiators) PDS (mounted on WAKE radiator) CAB (with LHP integrated, hence sunk to the wake radiator) All other subdetectors don’t need forced convection cooling, free convection being sufficient.
