Abstract
We describe progress toward realizing a new architecture for focal plane arrays for the Submillimeter and Far-Infrared (FIR) bands. This architecture is based on a detector design utilizing distributed hot-electron transition edge sensors (TES) coupled to slot antenna elements. Arrays utilizing this type of detector can be considerably easier to manufacture than membrane-isolated TES arrays, because the need for micro-machining is eliminated. We present background and rationale for this new array architecture and details of a new antenna design for an imaging polarimeter, which yields greater bandwidth than past designs. In addition, we describe a cryogenic facility for testing these arrays.
