CMB-S4 will build on the work done by the current generation instruments to obtain even more precise measurements of CMB polarization across a wide range of angular scales. The primary science goals include searching for evidence of inflation, measuring the number of light relativistic particle species, mapping the distribution of matter in the Universe, and studying transient microwave sources. Realizing these goals requires a combination of large and small aperture telescopes optimized for different purposes. Members of the Nagy lab are contributing the several different areas of the project including understanding instrumental systematics, building hardware to characterize detector modules, and developing calibration equipment for the large aperture telescopes.
