Abstract:
NOAO is testing Scientific Imaging Technologies, Inc. (SITe) thinned
backside 2k by 4k charge coupled devices (CCDs) to
be used at KPNO and CTIO. NOAO's Mosaics will use as the basic "tile" the
SITe ST-002A CCD Imager. These CCDs will
be used to upgrade the wide field Mosaic imager now in use at KPNO's
4-Meter Mayall telescope and 0.9-Meter telescope.
SITe 2k by 4k CCDs will also be used in MOSAIC II now under construction for
CTIO's 4-Meter Blanco telescope.
Additionally NOAO will implement 2 Mini-Mosaics in the two device 4K by 4K
configuration. The first of the ST-002As
arrived in mid August 97 and this paper will discuss test results of all
devices received and tested prior to publication.
Additionally this paper will discuss the mounting methods of Mosaics. This
will include; geometric stability, techniques used
for measuring CCD surface flatness and co-planer requirements for NOAO's
Mosaic Instruments
