Abstract:

The cosmic microwave background (CMB) continues to reveal new aspects of the large scale universe. For example, current projects are searching for evidence of primordial gravitational waves, for signatures sensitive to the sum of the neutrino masses, and for further understanding of the formation and growth of large structures under the influence of gravity in the accelerating universe. Technologies for ground-based and balloon-borne instruments measuring the polarization of the CMB have been well established and advanced in the last decade.

In this talk, I will focus on the instrumentation on these state-of-the-art arrays, especially on ACTPol, Advanced ACTPol and future stage-3 and stage-4 experiments.
