Abstract

MUSTANG, the MUltiplexed SQUID TES Array at Ninety GHz, is an 8 by 8 array of TES bolometers designed as a user instrument for the 100 m diameter Green Bank radio telescope (GBT). MUSTANG is the GBT's first 90 GHz instrument and its first focal plane array. As a continuum receiver on a large single dish, MUSTANG offers a unique combination of 8 arcsecond angular resolution and high sensitivity to extended structure.

In this poster we present an overview of MUSTANG. Observations of a range of objects including M87 and the Crab nebula will be used to illustrate MUSTANG's capabilities. Our first scientific observations in the spring of 2008 were of the Orion star forming region. These results will be presented in greater detail in a separate talk by Philip Korngut.

Currently, work is under way to improve the high frequency performance of the GBT and there are plans to increase MUSTANG's sensitivity further. A paper containing more technical details will appear in the proceedings of the SPIE conference on astronomical instrumentation (Dicker et. al. 2008).

MUSTANG will be available for proposals by the general astronomical community in the winter high frequency season of 2008/2009. Calls for proposals will be announced at NRAO's website, www.gb.nrao.edu.
