PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

NAME SMT MPIFR 19-CHANNEL BOLOMETER
TYPE RADIOMETER
DESCRIPTION The Submillimeter Telescope (SMT) Max Planck Institute fur Radioastronomie (MPIfR)19-channel bolometer was developed at MPIfR Bonn by E. Kresya and collaborators. Itwas in use at the Heinrich Hertz Submillimeter Telescope (SMT) until it wasdecommissioned sometime after mid-2004. The 19 channels of the array are arranged intwo concentric hexagons around the central channel. The azimuth distance between twoadjacent channels is about 50 arcsec and the maximum beam separation is about 200arcsec.The bandpass of the bolometer (delta nu over nu) is approximately 0.15. Thesensitivity extends from 310 to 380 GHz with peak sensitivity at 340-345 GHz. Thebeam size at this frequency is 23 arcseconds.In the submillimeter range, most of the noise is due to the atmosphere. With properdata reduction, the atmospheric noise can be eliminated to a certain degree. Theremaining noise level is about 600 mJy / sqrt(sec) per channel.This information has been taken from Chamberlain et al.
