Superconducting Transition edge detectors(TES)

Superconducting Transition edge detectors(Transition Edge sensor: TES)TheUsing a change in steep resistance value when the superconductor is a transition to the normal conductor、There the energy of X-ray photons at the detector which measures with ultrahigh precision。Metropolitan University Astrophysics Laboratory、Space Science Institute、In cooperation with domestic and foreign research institutes and universities of Kanazawa University, etc.、We are developing the TES detector。

Silicon detectors have been used frequently heretofore、For the energy resolution of a about 120eV、You can exceed it be more than one order of magnitude in the TES detector。I have to try, such as a variety of sizes and the number of pixels and processing methods so far。

Toward a better stable performance、Also it has continued extensive research current。State-of-the-art experimental techniques(Superconducting properties、Cryogenic experimental techniques、Micro-machine technology, such as)By making full use of the、Produced with their own hands、It aims to be carried out until the performance evaluation。

MEMS mirror

The cosmic X-ray telescope、Since the refractive index of the material to X-rays slightly smaller than 1、1Grazing incidence optics by using total reflection incident in less than one.It has been used in general。The current process(Grinding、Replica method、Foil method, or the like)In、Weight increases、It will also be enormous launch cost。there、We are making full use of state-of-the-art technology、Light and we are challenge to the development of good X-ray telescope-performance。

Micromachine technology、The so-called MEMS(Micro Electro Mechanicl Systems: MMS and pronunciation)We applied the technology to the X-ray mirror。And MEMS is、Micron, such as semiconductor, including silicon(11 / 1000 mm)Is the technology to be processed in size。

In fact it was designed and built as an optical system、We were able to get an image of almost as expected。This principle world's lightest X-ray optical system by using the MEMS fabrication techniques have demonstrated that that can be achieved(Ezoe other 2006Etc.)。

Currently、We finally developing towards the Space Applications。GEO-X satellite(Earth's magnetosphere visualization of satellite)Studying specific satellite missions etc.、2020We aim to space applications before and after the year。
