PAUCammosaic 150 Mpixel

  • Scientific goal:
    • Study the physics of the accelerating universe
    • Method: precision photo-z (48 narrow band filters)
    • Camera:
    • 18 CCDs (Hamamatsu Photonics, HPK), 2kx4k
    • high quantum efficiency in near infrared
    • there is not a filter wheel
    • filters are automatically positioned above CCDs by means of
    • 14 mobile segmented filter trays operating in vacuum
    • cryostat made of carbon fiber
    • William Herschel Telescope (La Palma) in 2014
    • also offered to the astronomical community as a facility
