“Rain drops keep falling on our heads”
The MONSOON development program continues and we report on the current status of, and the future plans for this project.
The Forecast : Warm deluges of success with some cold showers of reality
Taking a photon shower
Not enough time to catch all the photons we need !
Big instruments – Big focal planes
More photons !! UV – VIS – NIR – MIR.
MONSOON designed to accommodate these requirements
So; where is MONSOON ?

established February 2005
Motivation:
1). Replace unreliable, high maintenance, or obsolete CCD controllers.
2). Unify detector controller architectures to reduce maintenance burden.
3). Apply to new instrumentation without risk of ‘single source’ components.

Photons keep falling on our heads,
And we don’t have a cheap detector to catch them all,
Crying just won’t help,
The challengeis Rockwell
or Raytheonto show us
how do it in … SDW2008 !

Aren’t we just so happy about MONSOON?
So happy we could sing about it !!All together now
