GISMO consists of '''8x16 pixels''' with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. The nominal bandwidth is 140-162 GHz (FWHM), pixels are spaced by '''13.75"''', the telescope HPBW is '''16.7"'''. The sensitivity has improved relative to the April 2011 run to a media value of about '''14 mJy sqrt(sec)''' (cf. reports below). The field-of-view is ''' 1.8'x3.7' '''. Two standard observing modes are offered, Lissajous curves and on-the-fly scans. Both work in total power, without switching the secondary. An automated pipeline merges the GISMO data with the telescope data streams to create FITS files which are automatically processed by the reduction software crush to create logs, pointing results, and a first quick view of the data. Typical overheads for single science targets on the sky are 60%. The relative flux stability is about 8%. |
GISMO consists of '''8x16 pixels''' with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. The nominal bandwidth is centred at 2 mm (150 GHz). The is shown in Figure 1. Pixels are spaced by '''13.75"''' and the telescope HPBW is '''16.7"'''. The sensitivity is about '''14 mJy sqrt(sec)''' . The field-of-view is ''' 1.8'x3.7' '''.

GISMO
The Goddard-IRAM Superconducting 2mm Observer (GISMO) is a bolometer camera for the IRAM 30m telescope. It has been build by Goddard Space Flight Center, in Greenbelt, Maryland under the lead of Johannes Staguhn.
Contents
Overview
GISMO consists of 8x16 pixels with super conducting transition edge sensors (TES). The TES are read out by time domain SQUID multiplexers built at the National Institute for Standards (NIST), in Boulder, Colorado. The nominal bandwidth is centred at 2 mm (150 GHz). The is shown in Figure 1. Pixels are spaced by 13.75" and the telescope HPBW is 16.7". The sensitivity is about 14 mJy sqrt(sec) . The field-of-view is 1.8'x3.7' . Two standard observing modes are offered, Lissajous curves and on-the-fly scans. Both work in total power, without switching the secondary. An automated pipeline merges the GISMO data with the telescope data streams to create FITS files which are automatically processed by the reduction software crush to create logs, pointing results, and a first quick view of the data. Typical overheads for single science targets on the sky are 60%. The relative flux stability is about 8%. GISMO has been available to observers since the winter semester 2011/12.
