Bolometer Detector The detector used in our experiments is an InSb hot electron bolometer cooled to liquid helium temperatures via an inner dewar of liquid helium surrounded by an outer jacket of liquid nitrogen. The millimeter-waves are converted to a voltage signal, which passes through a low-noise preamplifier before being processed by a lock-in amplifier. Below is a photograph of one of the bolometer detectors used by the Ziurys Group.
