摘要：

In the X-ray astrophysics community, the desire for wide-field, high-resolution? X-ray imaging spectrometers has been growing for some time. We present a concept for such a detector called a Position-Sensing: Transition-edge sensor (PoST). A PoST is a calorimeter consisting of two Transition-Edge Sensors (TESs) on the ends of a long absorber to do one dimensional imaging spectroscopy. Comparing the rise time and energy estimates obtained from each TES for a given event, the position of that event in the PoST is determined. Energy is inferred front the sum of the two signals on the TESs. We have designed 7, 15, and 32 pixel PoSTs using our Mo/Au TESs and bismuth absorbers. We discuss the theory, modeling, operation and readout of PoSTs and the latest results from our development.
