Abstract

TolTEC is a 3-band millimeter-wave imaging polarimeter scheduled for deployment to the Large Millimeter Telescope (LMT) in January 2020. TolTEC consists of three, kilopixel-scale, monolithic arrays of microwave kinetic inductance detectors (MKIDs), together comprising over 7,000 polarization sensitive detectors. Here we describe many of the unique aspects of the TolTEC all-silicon focal plane design. We then present both laboratory and fully integrated in-receiver measurements in the lab with which we characterize the optical, resonator, and noise properties of the arrays.
