  1. Thermal controlGSE at KSC

  2. 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. 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.

  4. Type A Fans • Quantity 12 • Diameter > 0.45 m • Flow Rate 4100 m3/h • Unit power (reference value) 135 W • Voltage 110 V • AC supply Frequency 60 Hz

  5. 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

  9. Type B Fans • Quantity 3 • Diameter >0.18 m • Flow Rate 740 m3/h • Unit power (reference value) 50 W • Voltage 110 V • AC supply Frequency 60 Hz

  10. Type B fans usage • One fan is dedicated to the PDS, and it shall work at the same time of the Wake radiator fans. • The other two fans shall blow air to the CAB on two of its faces (wake and starboard).

  12. Quality stamp on COTS • All fans will be commercial off the shelf (COTS) and have the European “CE” quality symbol on it. • The supplier of the fans is TBD.
