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.

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 dont need forced
  convection cooling, free convection being
  sufficient.

• 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

Type B Fans

• Quantity 3
• Diameter gt0.18 m
• Flow Rate 740 m3/h
• Unit power (reference value) 50 W
• Voltage 110 V
• AC supply Frequency 60 Hz

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).

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.
