T250 Camera
 

The camera and telescope are being designed in parallel. The camera contains: the filter trays, an optically neutral entrance window, the cryostat, cryo-cooling systems, the detector array, and the electronics and control system.

For the CCDs, we have converged on e2V's large-format chips, which are 9k × 9k pixels, 9μm/pixel. The mosaic will be an arrangement of 14 units. The filters (one for each CCD) will be distributed in four different filter holder trays containing, 14 filters each. The filters will be placed as close as possible to the cryostat entrance window.

Considering a pixel to pixel separation between CCDs of c=15 mm we obtain a focal panel coverage efficiency of 71% using 14 CCDs.
 

T80 Camera

The pixel scale for this camera will be 0.501′′ /pixel. The large-format CCD then allows to cover up FoV(diameter) = 2.07 deg. The minimum required FoV is diameter = 1.7 deg. The Camera consists of a filter system of 12 filters, including the filter exchange mechanism (filter wheel, juke-box, etc.), the entrance window, cryostat, one 9k x 9k detector, and the corresponding electronics and control system. The T80 Camera communicates with the Telescope Control System and should be a benchmark for the T250 camera.
