The Multiplexed Squid Tes Array at Ninety Gigahertz (Mustang) Abstract The Multiplexed SQUID/TES Array at Ninety Gigahertz (MUSTANG) is a bolometric continuum imaging camera designed to operate at the Gregorian focus of the 100m Green Bank Telescope (GBT) in Pocahontas county, West Virginia. The combination of the GBT's large collecting area and the 8x8 array of transition edge sensors at the heart of MUSTANG allows for deep imaging at 10'' resolution at 90GHz. The MUSTANG receiver is now a facility instrument of the National Radio Astronomy Observatory available to the general astronomical community. The 3.3mm continuum passband is useful to access a large range of Galactic and extra-Galactic astrophysics. Sources with synchrotron, free-free and thermal blackbody emission can be detected at 3.3mm. Of particular interest is the Sunyaev Zel'dovich effect in clusters of galaxies, which arises from the inverse Compton scattering of CMB photons off hot electrons in the intra-cluster medium. In the MUSTANG band, the effect is observationally manifested as an artificial decrement in power on the sky in the direction of the cluster.
