USNO Robotic Astrometric Telescope
URAT: the Detector
- new camera is based on 10k CCD from Semiconductor Technology Associates (STA), model ST1600B
- backside chips, thinning is underway at Univ.of Arizona (M. Lesser)
- 10,560 by 10,560 pixels of 9 by 9 micons, over 111 Mpx
- 16 output registers
- read at 1 Mpx/sec
- option for clocked anti-blooming to extend dynamic range at bright end for astrometry
- A milestone was passed on 29 June 2010 with successful testing of a fully functional back-side
illuminated 10K detector at Semiconductors Technology Associates (STA).
A single 10k chip (STA1600B), measuring over 95 mm on a side, is shown above, in comparison with a Leica digital camera.
The picture above shows the backside of the 10k chip mounting.
This screenshot shows 1/4 of the area of a fully functional
10k chip (STA1600B). The black bars separating the 4 sections
shown here are overscan areas of this flat-field image.
This detector is a back-illuminated device, thinned by M.Lesser
at Univ. of Arizona. The raw image was obtained by K.Boggs
using the Aura electronics from G.Bredthauer, Semiconductor
Technology Associates (STA).
All 16 outputs working on the thinned 10k detector.
