Description
SPT-3G is an ambitious focal plane upgrade for the South Pole Telescope
(SPT) platform. The SPT is one of the world's premier mm-wave
observatories and has been optimized for precision measurements of the
Cosmic Microwave Background. In this talk, I will discuss ongoing research
and development of multi-chroic Transition Edge Sensor (TES) bolometer
arrays which will be the detector technology for the SPT-3G focal plane. I
will present details regarding our investigation and optimization of the
detector's thermal circuitry, transition profile, and superconducting
microstrip transmission line.
