CSL - Focal V

CSL - Focal V

 FOCAL 5 (Centre Spatial de Liège)
AMOS has been prime contractor for the design and manufacturing of the IAL Space (now CSL) space test centre equipped with a vacuum optical bench and all its peripheral equipment. This system for optical tests under vacuum of satellite payloads is composed of the following elements :

• Building for 50 persons ;
• Clean room of 27 x 18 x 10 m, class 100 000 ;
• Vacuum vessel of 5 m diameter with an automatic system to open and close the main lids, an optical table made of welded stainless steel boxes, interfaced with a 350 tons concrete seismic bloc ;
• Laminar flow wall, class 100, in the preparation area of the spacecrafts ;
• Thermal system which controls the temperature of 10 fluids. The temperature of these fluids can be set between + 100 and - 170°C with an accuracy of 0,2°C.

The complete system is controlled by processor.

Vacuum vessel :

  • Dimensions : length : 6 m + 2 lids of 1,4 m depth ;
  • Diameter : 5 m ;
  • Materials : blasted stainless steel.

Optical table :

  • Dimensions : length : 6,8 m, width : 1,8 m, thickness : 0,35 m ;
  • Flatness : 10 µm/m ;
  • Stability : 3.10-6 g.

Pumping :

  • Rough : rotary : 2 x 250 m3/h ;
  • Roots : 1850 and 6200 m3/h ;
  • High vacuum : cryogenic : 100 000 l/s ;
  • Turbomolecular : 1500 l/s ;
  • Interseal : rotary : 60 m3/h.

Thermal system :

  • 10 independent supplies with gazeous nitrogen ;
  • Range : from + 100 to -170°C ;
  • Stability : 0,2°C.


Clean room :

  • Class 100 000 ;
  • Temperature : 20°C ± 2°C ;
  • Humidity : 50 % ± 5% ;
  • Laminar flow wall, class 100, of 25 m2.
