Detector systems Guider cameras - 4
cameras at LCO, 5 more to be fabricated this
year - 3 cameras for IMACS by end of 2001?
Science arrays - All CCDs in house - Dewar
and detector system mechanics in house - First
OCIW science controller (with 1 CCD) operating
34
Detector systems continued Five science
cameras planned for assembly in 2001 - 2K x 4K
lab system - Red and Blue 2K x 4K cameras for
MIKE - 4K x 4K camera - IMACS 8K x 8K Jorge
Estrada now assisting with electronics
assembly of the guiders and eventually, the
science arrays.
