Note the depiction of the ghost of the old Tektronix CCD.
Please see the links in this sentence for the sake of
nomenclature of the 2009 and 2011 amplifiers and the
canonical manner in which they are wired.
Please see the link in this sentence for the sake of
nomenclature of the 2021 detector amplifiers.
This diagram is a synthesis of the contents of what should be
several separate diagrams and documents.
These diagrams documenting the LRIS red focal planes
should not include
-
the device names of the CCDs
-
the designations of the video inputs
-
the designations of the amplifier types
-
the PANE coordinates
This is a draft. It all deserves double checking.
As of 2009-03-05 Steve Allen and Bob Kibrick believe that this shows
the definitive nomenclature for the CCD locations and the amplifier
locations for the 2009 LRIS mosaic.
We do not remember whether we checked this for the 2011 replacement mosaic.
This page now includes the 2021 replacement.
Please let me know if you find anything that seems awry.
We do not remember why the 2011 replacement of the 2009 mosaic
is drawn with the detectors rotated by 180 degrees.
The extra information in this diagram includes
-
the names of the particular LLNL 2k*4k CCDs which were in the
2009 and 2011 LRIS science mosaics
-
the names of the amplifiers on the LLNL 2k*4k CCDs as they are
described in the spec sheets for those detectors
-
the names of the video inputs as they are connected via the
current permutation of video cables
The PANE coordinates can be redefined, but the current
coordinates provide a match between the red and blue sides
of LRIS. It seems best to maintain that correspondence
in order to avoid confusion.
