The Atacama Cosmology Telescope (ACT) makes high angular resolution measurements of anisotropies in the Cosmic Microwave Background (CMB) at millimeter wavelengths. We describe ACTPol, an upgraded receiver for ACT, which uses feedhorn-coupled, polarization-sensitive detector arrays, a 3 degrees field of view, 100 mK cryogenics with continuous cooling, and meta material antireflection coatings. ACTPol comprises three arrays with separate cryogenic optics: two arrays at a central frequency of 148 GHz and one array operating simultaneously at both 97 GHz and 148 GHz. The combined instrument sensitivity, angular resolution, and sky coverage are optimized for measuring angular power spectra, clusters via the thermal Sunyaev-Zel'dovich (SZ) and kinetic SZ signals, and CMB lensing due to large-scale structure. The receiver was commissioned with its first 148 GHz array in 2013, observed with both 148 GHz arrays in 2014, and has recently completed its first full season of operations with the full suite of three arrays. This paper provides an overview of the design and initial performance of the receiver and related systems.

| ACT is on the Chajnantor Science preserve, which was made possible by the Chilean Comision Nacional de Investigacion Cientifica y Tecnologica. We are grateful for the assistance we received at various times from the ABS, ALMA, APEX, ASTE, and POLARBEAR groups. The PWV data come from the public APEX weather site. Field operations were based at the Don Esteban (operated by Astro-Norte) and RadioSky facilities. This work was supported by the U.S. National Science Foundation through awards AST-0408698 and AST-0965625. Funding was also provided by Princeton University, the University of Pennsylvania, Cornell University, the Wilkinson Fund, and the Mishrahi Gift. The development of multichroic detectors and lenses was supported by NASA grants NNX13AE56G and NNX14AB58G. C.M. acknowledges support from NASA grant NNX12AM32H. B.S., B.K., C.M., E.G., K.C., J.W., and S.M.S. received funding from NASA Space Technology Research Fellowships. R.D. thanks CONICYT for grants FONDECYT 1141113 and Anillo ACT-1417. |
