“…The Position Sensitive TESs (PoST) concept addresses these issues by providing both a position and an energy measurement of the absorbed x-ray. This is done by attaching a TES to either end of a chain of absorbers, ∼ 10 pixels long, and comparing the signals seen in the two TESs in order to determine the position of the absorbed x-ray [8]. Figure 6 shows a schematic of the PoST; the vertical stack of absorber, TES, and the thermal impedances in between is equivalent to a single pixel microcalorimeter.…”

Transition Edge Sensors (TES) have found applications as astronomical detectors ranging from the microwave to the gamma ray energy bands. Each energy band, however, imposes a different set of requirements on the TES such as energy and timing resolution, focal plane coverage, and the mechanisms by which the signal is coupled to the detector. This paper focuses on the development of TESs optimized for the 0.1-10 keV energy range at the NASA Goddard Space Flight Center. Such detectors are suitable candidates for some of the upcoming X-ray observatories such as NeXT and Constellation-X. Ongoing efforts at producing, characterizing, and modeling such devices, as well as the latest results, are discussed.

“…The construction of (32 Â 32) pixel arrays is still a major challenge [6][7][8]. An alternative is to use a position-sensitive detector incorporating two or more TESs on a single absorber and using ''heat division'' as the position-sensing principle [9][10][11][12][13]. The photon energy is estimated from the sum of the TES signals and the event position is inferred from the normalised difference between the signals.…”
