Big innovations in a small instrument: technical challenges in a new CCD system design for the Automated Patrol Telescope
2008
We describe the design of a new CCD system delivered to the Automated Patrol Telescope at Siding Springs NSW Australia operated by UNSW. A very fast beam (f/1) with a mosaic of two MITLL CCID-34 detectors placed only 1 mm behind the field flattener which also serves as the dewar window, have called for innovative engineering solutions. This paper describes the design and procedure of the field-flattener mounting, differential screw adjustable detector mount and dewar suspension on the external ring providing tip/tilt and focus adjustment.
