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…
First-principles response simulation of wide-gap CdTe-DSDs for the FOXSI solar sounding rocket experiment
Shunsaku Nagasawa, Takahiro Minami, Tadayuki Takahashi +1
We have developed a wide-gap CdTe double-sided strip detector (CdTe-DSD) for the fourth and fifth flights of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXS…
Signal processing and data acquisition system for the BTO detectors onboard COSI
Shunsaku Nagasawa, Tadayuki Takahashi, Kazuhiro Nakazawa +15
The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV…
Imaging and Spectral Performance of a Wide-gap CdTe Double-Sided Strip Detector
Shunsaku Nagasawa, Takahiro Minami, Shin Watanabe +1
The fourth flight of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXSI-4) aimed to achieve the first imaging spectroscopic observations of mid-to-large class…
A Study of Afterglow Signatures in NaI and CsI Scintillator Modules for the Background and Transient Observer Instrument on COSI
Hannah Gulick, Hiroki Yoneda, Tadayuki Takahashi +15
We present measurements of the afterglow signatures in NaI(Tl) and CsI(Tl) detector modules as part of the Background and Transient Observer (BTO) mission detector trade-study. BTO…
The energy dependence of cluster size and its physical processes in the proton measurement with TimePix3 silicon detector
Naoki Itoh, Hugo Allaire, Tokihiro Ikeda +7
We investigated the energy dependence of the number of triggered pixels, or cluster size, when charged particles are detected using the TimePix3 detector with a silicon sensor. We…
