The TRUCE Collaboration

 
 

We are a collaboration of several institutions whose purpose is to design and test exciting next-generation millimeter wave pixels for studies of the Cosmic Microwave Background (CMB).  Optimized for observations at 150 GHz, each pixel contains two optically coupled transition edge sensor (TES) bolometers, both sensitive to orthogonal polarization modes.  The pixels also boast band-defining filters built into the device.  These pixels are slated for use in several upcoming next-generation CMB polarization experiments, including the Atacama B-Mode Search (ABS), the Atacama Cosmology Telescope (ACT)pol, and South Pole Telescope (SPT)pol experiments.  To learn more about what our pixels are and how they operate, take a look at the papers below.
