TELESCOPE DETAILS

 

During CCAT Prime’s scientific lifetime, mm/submm detector arrays will become available that are many times larger than those in present-day cameras. To accommodate next-generation, large-format cameras and enable large-scale galaxy and molecular cloud surveys, the optical design is optimized for a wide field of view.  The baseline telescope is of a crossed-Dragone design[1] with a novel AZ-EL mount[2], capable of sufficient throughput to illuminate > 105 detectors.  Multiple instruments will be supported and observations will be fully remote control.  The mirror surfaces (all passive) will be made of machined aluminum tiles on a thermally stable CFRP support structure.
