Abstract

In order to improve pixel count and collecting area, future TES x-ray focal planes require pixels with both a higher coverage of the active area and compatibility with in-focal-plane multiplexing. We anticipate these improvements by developing a pixel with an “overhanging” geometry that allows room for multiplexing elements underneath the absorber simultaneously with the possibility of near full coverage of the focal plane. We have fabricated and tested such a pixel. We have demonstrated a spectroscopic resolution of 3.2 eV FWHM at 5.9 keV, thereby showing that it is suitable for applications in the near future.
