  MUSCAT is a large format mm-wave camera scheduled for installation on the
Large Millimeter Telescope Alfonso Serrano (LMT) in 2018. The MUSCAT focal
plane is based on an array of horn coupled lumped-element kinetic inductance
detectors optimised for coupling to the 1.1mm atmospheric window. The detectors
are fed with fully baffled reflective optics to minimize stray-light
contamination. This combination will enable background-limited performance at
1.1 mm across the full 4 arcminute field-of-view of the LMT. The easily
accessible focal plane will be cooled to 100 mK with a new closed cycle
miniature dilution refrigerator that permits fully continuous operation. The
MUSCAT instrument will demonstrate the science capabilities of the LMT through
two relatively short science programmes to provide high resolution follow-up
surveys of Galactic and extra-galactic sources previously observed with the
Herschel space observatory, after the initial observing campaigns. In this
paper, we will provide an overview of the overall instrument design as well as
an update on progress and scheduled installation on the LMT.
