The Cerro Chajnantor Atacama Telescope-prime is a submillimeter wavelength telescope designed for very wide field observing. This 6-meter aperture telescope will begin operations in Chile in 2022, carrying out several large-area surveys with a mapping speed unchallenged by any current or near-future facilities in the 150 to 1500 GHz telluric window. These surveys will be combined with data from other facilities to trace the first galaxies as they reionize the Universe, to constrain the physics driving the current acceleration of the cosmic expansion rate, to determine the sum of neutrino masses via observations of foreground effects on the Cosmic Microwave Background, and to use the distribution of dusty galaxies to test inflation and search for primordial gravitational waves. Fich is the leader of the Canadian CCAT-p team that holds a 20% share of the facility.
