  1. MONSOONImage Acquisition System “Rain drops keep falling on our heads” Peter Moore(1) and Gustavo Rahmer(2) (1)National Optical Astronomy Observatory (2)Cerro Tololo Inter-American Observatory 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

  2. 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 ?

  3. Where we’re at: 350 400 1000 1050 1100 2500

  8. Open Source Release Open Source Release – November 2004 This is an Open License Agreement that allows you access to the complete technical information available for MONSOON. You must, for legal peace of mind, agree to the terms of this license. Essentially, by clicking the "Accept" button at the foot of this page, you agree to make any contributions you may make to the MONSOON technology available to others without hindrance and surrender all rights to patent claims to any of the covered technology - including the original source. In addition, the license explicitly absolves NOAO from any warranty or liability for the use of, or fitness of purpose for, MONSOON technology. The good news is that the license doesn't stop you from using (or abusing) the technology, or building systems from the information, or even making a dollar from supplying this technology to others. In fact you are encouraged to do all of these things ! Accept

  10. Cold shower Collaborations !! MONSTEROID LSST NOAO WIYN STSci UIUC / FERMILAB QUOTA /ODI • Hardware Test and Dev. • Firmware Dev. • Guide + Science Software Dev. DES : DeCam • 12 Channel CCD Video Board • Firmware Development WHIRC • Sequencer Code Dev. • Detector (Virgo) Interface MONSOON - Collaboration History - Cold shower #2: - Each ‘collaboration’ effort requires explicit support which in turn, requires resources. However, collaborations that ‘stick’ are very productive !

  11. New Toys – The future MONSOON ‘ORANGE’ OPEN SOURCE & IN SERVICE DECam Requirements established May 2002 NEWFIRM + 11 OTHERS MONSOON ‘GREEN’ … HIGHER DENSITY LESS POWER Requirements established March 2004 ODI 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. REPACKAGED LOWER COST TORRENT Requirements established February 2005

  12. Aren’t we just so happy about MONSOON? So happy we could sing about it !! All together now … Photons keep falling on our heads, And we don’t have a cheap detector to catch them all, Crying just won’t help, The challenge is for Rockwell or Raytheon to show us how to do it in … SDW2008 !
