At the Physical Society of Japan、2018The "Physical Society of Japan Student Excellence Presentation Award" has been awarded since the autumn meeting.。Mr. Ishi is in the cosmic ray / astrophysics area、Oral presentation with the following contents。

title : Development of curved Bragg reflection type X-ray polarimeter using silicon high temperature plastic deformation technology

The Bragg reflection type polarimeter has high polarization detection sensitivity, but on the other hand、Unless the energy meets Bragg's condition、Unable to detect polarized light、To collect more light、I had to arrange the crystals in a mosaic。We use the high temperature plastic deformation technology that originated in Japan、By plastically bending the silicon crystal、It was a challenge for Bragg's reflective polarimeter、We are developing a unique polarizing meter that can expand the energy band and collect light.。In this study、JAXA Institute for Space Studies 30 m at the beamline、Polarized X-rays on curved silicon crystals actually manufactured by high-temperature plastic deformation technology (Fe Kα 6.4 keV) Irradiate、This method is the first in the world、Bragg reflection intensity variation (Modulation) Succeeded in getting。from now on、Including specific satellite studies、For practical use、I look forward to further progress。
