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

AMS Ground Safety Review II Sept – 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.

AMS Ground Safety Review II Sept – 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.

AMS Ground Safety Review II Sept – KSC 5 AMS 02 –Thermal Control System Design Four fans will blow to the electronic units mounted on the Ram radiator, having their axis parallel to the radiator Four fans will blow to the electronic units mounted on the Wake radiator, having their axis parallel to the radiator Four fans will blow the Zenith Radiator, having their axis parallel to the 4 zenith radiator quadrants
