Abstract

Polarbear-2 is a next-generation receiver for precision measurements of the polarization of the cosmic mi-crowave background (Cosmic Microwave Background (CMB)). Scheduled to deploy in early 2015, it will observealongside the existing Polarbear-1 receiver, on a new telescope in the Simons Arrayon Cerro Toco in theAtacama desert of Chile. For increased sensitivity, it will feature a larger area focal plane, with a total of 7,588 polarization sensitive antenna-coupled Transition Edge Sensor (TES) bolometers, with a design sensitivity of 4.1 μKs. The focal plane will be cooled to 250 milliKelvin, and the bolometers will be read-out with 40 × frequency domain multiplexing, with 36 optical bolome..
