Title : Future prospects in high resolution energy dispersive spectroscopy with Superconducting Transition Edge Sensor X-ray microcalorimeters

Abstract :
Superconducting Transition Edge Sensors (TES) are very promising X-ray detectors that enable sub-eV energy dispersive X-ray spectroscopy.
In this seminar we introduce our research and development work at the University of Tokyo and show future prospects of ultra-high energy resolution X-ray spectroscopy with large format array TES microcalorimeters.
At this moment, we have achieved 30eV energy resolution for new detector structure using large X-ray absorbers. Actually measured energy resolution of better than 7 eV has been achieved by irradiation of external beam of synchrotron radiation. Furthermore, we have demonstrated the 1MeV region
spectroscopy with large lead absorber for the first time.
