National Institute of Advanced Industrial Science and Technology, in which Ryodai Hayakawa, a second-year doctoral student at Tokyo Metropolitan University, plays a central role(AIST)、JAXA Institute of Space Science(ISAS/JAXA)、Institute of Space and Astronautical Science, Netherlands(NOSE) And our joint research、A paper on signal multiplexing and readout technology from TES using microwaves、Applied Physiscs Letter (APL) It was published in。The space experiment group of Tokyo Metropolitan University has participated since the launch of the refrigerator system used in this experiment.、Taking a step forward in space observation using TES in the future。

Microwave is a multiplexed readout technology、It is a next-generation multiplexed readout technology that can read signals from a detector with a high number of pixels with a small number of wires, unlike the conventional multiplex readout technology.、It is expected to be used in next-generation X-ray astronomical satellites, etc.、Development is underway around the world, centered on the US NIST。In our group、Using this technology、Simultaneous readout of 38 elements in SRON TES calorimeter array、9Succeeded in signal acquisition under the world's highest level of low noise of pA / √HZ、5.9For keV X-rays、2.79Achieved high energy resolution of ± 0.09 eV。Detail is、Please read the following。
