Abstract :
Signal shapes and noise characteristics of an asymmetrical ten-pixel Ir/Au-TES have been studied. The asymmetric design may be effective to realize an imaging spectrometer. Distinct two exponential decays observed for X-ray events are consistent with a two-step R–T curve. A theoretical thermal model for noise in multi-pixel devices reasonably explains the experimental data.
