Abstract
The Sub-millimeter Common-User Bolometer Array 2 (SCUBA-2) large format Transition Edge Sensor (TES) arrays are optimized to maximize mapping speed with two commissioned regular observing scan patterns. The ancillary instruments POLarimeter 2 (POL-2) and Fourier Transform Spectrometer 2 (FTS-2) impose different demands on the arrays compared to regular stand-alone SCUBA-2 observing. This includes a change in the background optical power loading on the arrays and a requirement for a larger dynamic range from the individual TES bolometers. In this paper, we discuss the process for optimizing the TES arrays specifically for POL-2 and FTS-2 operations and report the improvements that we have obtained.
