SUMMARY:Development of Large Scale Detector Arrays for Cosmic Microwav
 e Background Science\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Tom
  Cecil\, Argonne National Lab
DESCRIPTION:The Cosmic Microwave Background (CMB) provides a unique wi
 ndow on the physics of the early Universe and measurements of CMB pola
 rization offer the potential of a definitive test of inflation. Many o
 f the advances in the field of CMB science have been enabled by advanc
 es in detector technology. Ground-based CMB experiments have seen orde
 r of magnitude increases in detector count with each subsequent stage 
 with current stage-3 experiments fielding ~10K detectors. In this talk
  I will provide an overview of CMB detector development at Argonne. Fo
 r over a decade we have been developing transition edge sensors (TES) 
 through our collaboration with the South Pole Telescope\, resulting in
  the delivery of detectors for the SPTpol and SPT-3G experiments. Curr
 ent efforts are focused on developing detectors for the CMB-S4 experim
 ent\, which is expected to have ~ 300K detectors. I will discuss issue
 s of detector design\, fabrication\, and testing necessary to realize 
 the large detector counts of these experiments.
