Prime-Cam: A first-light instrument for the CCAT-prime telescope

Understand

CCAT-prime will be a 6-meter aperture telescope operating from sub-mm to mm wavelengths, located at 5600 meters elevation on Cerro Chajnantor in the Atacama Desert in Chile.

• Its novel crossed-Dragone optical design will deliver a high throughput, wide field of view capable of illuminating much larger arrays of sub-mm and mm detectors than can existing telescopes.
• We present an overview of the motivation and design of Prime-Cam, a first-light instrument for CCAT-prime.
• Prime-Cam will house seven instrument modules in a 1.8 meter diameter cryostat, cooled by a dilution refrigerator.
