  This is a system
  diagram of the DSOS. 
   | 
 
 
   | 
  The CSO consists
  in part of a 10.4 meter primary mirror. 
  The dish has 84 hexagonal panels made of aluminum epoxied onto a
  honeycomb backing that is mounted on a steel backing structure. 
   | 
 
 
   | 
  Simply by using
  the properties of the in-place steel rod standoff itself, the DSOS expands
  and contracts, without mechanical gears. The system does no harm to the
  original mechanical tune of the primary.  Turn the DSOS off and the dish goes back to it s original
  state.

   | 
  There are 99
  standoff assemblies which I will show in the next slides. Wiring and plumbing
  were routed to distribute the weight of the material as evenly as possible on
  the backing structure. 
   | 
 
 
   | 
  I split the dish
  into 4 quadrants. The different colored lines indicate the different
  quadrants. 
   | 
 
 
   | 
  The electronics
  are housed in 3 racks seen on the right. 
   | 
 
 
   | 
  The refrigerated
  baths, pumps, manifolds, and coolant lines, are shown here on both sides of
  the dish.
