Submillimeter Astrophysics group to return to APEX

July 28th, 2015

The submillimeter group is returning to APEX with their custom made spectrometer, ZEUS-2, for July-August.

ZEUS-2 is a grating spectrometer that the submillimeter group is currently building and that will be used on CSO, APEX, and (possibly) JCMT to observe emission lines in all submillimeter bands that are accessible from the ground. It is a new spectrometer that is based on our present instrument ZEUS, but differs significantly in several aspects that will greatly improve the sensitiviy and observing efficiency. ZEUS-2 will have:

• » "Dry" cryostat including pulse-tube cooler and dual stage ADR
• » Three arrays of transition-edge-sensed bolometers
• » Spatial imaging capabilities
