Numerical Investigation of Efficient Electron Acceleration at an Unsteady Solar Flare Loop-Top
Yoshiaki Sato, Takafumi Kaneko, Noriyuki Narukage +1
Using magnetohydrodynamic (MHD) fields and guiding-center test-particle calculations, this study investigates how time-dependent loop-top dynamics modulate the adiabatic energizati…
Development of Electroformed X-ray Optics Bridging Synchrotron Technology and Space Astronomy
Ryuto Fujii, Koki Sakuta, Kazuki Ampuku +21
We have developed X-ray telescope mirrors using an original electroforming replication technique established through the fabrication of millimeter-aperture, ultra-short-focal-lengt…
SpaceWire-based Data Acquisition Network for the Solar Flare Sounding Rocket Experiment FOXSI-4 and FOXSI-5
Shunsaku Nagasawa, Athanasios Pantazides, Kristopher Cooper +10
We developed a SpaceWire-based data acquisition (DAQ) system for the FOXSI-4 and FOXSI-5 sounding rocket experiments, which aim to observe solar flares with high sensitivity and dy…
Development of Solar Flare X-ray Polarimeter with Micro-Pixel CMOS Sensors
Kouichi Hagino, Tatsuaki Kato, Toshiya Iwata +10
We are developing an X-ray polarimeter using micro-pixel CMOS sensors for solar flare X-ray polarimetry. The system consists of a 2.5-m pixel CMOS image sensor with a 12.8$\tim…
