Verification of the Timing System for the X-ray Imaging and Spectroscopy Mission in the GPS Unsynchronized Mode

Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato +59

We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is…

Improvement of the Spatial Resolution of the ACIS Using Split Pixel Events

Hiroshi Tsunemi, Koji Mori, Emi Miyata +4

The position accuracy of X-ray photons on a CCD detector is generally believed to be limited by the CCD pixel size. While this is true in general, the position accuracy for X-ray e…
