Abstract :
To realize imaging X-ray spectroscopy with high-energy resolution, we proposed a new pixellated array of Ir-TES. In this type of device, the bias point of each pixel is slightly modified. Therefore the analysis of the pulse shape parameter, such as the pulse height, the rise time and the fall time of a signal pulse, can identify the incident pixel position. We have obtained 13 eV (FWHM) at 3 keV energy resolution and 80 μm position resolution for 10 pixel devices. At this moment we could successfully operate a 20 pixel device.
