A 90 GHz bolometer array for the Green Bank Telescope

摘要

The Penn Array Receiver (PAR) is a camera designed for rapid, high angular resolution imaging at 90 GHz (3.3 mm). When installed on the 100 m Green Bank Telescope it will have a 32″ x 32″ field of view and 8″ resolution. PAR has an eight by eight planar array of superconducting Transition Edge Sensor bolometers. Currently it is in the commissioning phase and after that it will become a user instrument capable of mapping a 5′ x 5′ area of sky to a noise level of 40μJy in one hour.
