SMT MPIfR 19-channel Bolometer Radiometer The Submillimeter Telescope (SMT) Max Planck Institute fur Radioastronomie (MPIfR) 19-channel bolometer was developed at MPIfR Bonn by E. Kresya and collaborators. It was in use at the Heinrich Hertz Submillimeter Telescope (SMT) until it was decommissioned sometime after mid-2004. The 19 channels of the array are arranged in two concentric hexagons around the central channel. The azimuth distance between two adjacent channels is about 50 arcsec and the maximum beam separation is about 200 arcsec. The bandpass of the bolometer (delta nu over nu) is approximately 0.15. The sensitivity extends from 310 to 380 GHz with peak sensitivity at 340-345 GHz. The beam size at this frequency is 23 arcseconds. In the submillimeter range, most of the noise is due to the atmosphere. With proper data reduction, the atmospheric noise can be eliminated to a certain degree. The remaining noise level is about 600 mJy / sqrt(sec) per channel. This information has been taken from Chamberlain et al. (2007) and from the MPIfR website (http://www.mpifr-bonn.mpg.de).
