We report on a new photon-counting detector possessing unprecedented spatial resolution, moderate spectral resolution and high background-rejection capability for 0.1-100 keV X-rays. It consists of...
Miyata, E., Kamazuka, T., Kouno, H., Mihara, M. Fukuda M., Matsuta, K., Tsunemi, H., ...
We have investigated the radiation damage effects on a CCD to be employed in the Japanese X-ray astronomy mission including the Monitor of All-sky X-ray Image (MAXI) onboard the International Space...
Miyata, E., Miki, M., Hiraga, J., Kouno, H., Yasui, K., Tsunemi, H., ...
We have employed a mesh experiment for back-illuminated (BI) CCDs. BI CCDs possess the same structure to those of FI CCDs. Since X-ray photons enter from the back surface of the CCD, a primary charge...
Direct X-ray Imaging of $\mu$m precision using Back-Illuminated CCD (2002)
Miyata, E., Miki, M., Tsunemi, H., Hiraga, J., Kouno, H., Miyaguchi, K.
A charge-coupled device (CCD) is a standard imager in optical region in which the image quality is limited by its pixel size. CCDs also function in X-ray region but with substantial differences in...
Sakano, M., Tomida, H., Matsuoka, M., Ueno, S., Komatsu, S., Shirasaki, Y., ...
Monitor of All-sky X-ray Image (MAXI) on the International Space Station (ISS) has two kinds of X-ray detectors: the Gas Slit Camera (GSC) and the Solid-state Slit Camera (SSC). SSC is an X-ray CCD...
Nonthermal X-Ray Emission from G266.2-1.2 (RX J0852.0-4622) (2001)
Slane, P., Hughes, J. P., Edgar, R. J., Plucinsky, P. P., Miyata, E., Aschenbach, B.
The newly discovered supernova remnant G266.2-1.2 (RX J0852.0-4622), along the line of sight to the Vela SNR, was observed with ASCA for 120 ks. We find that the X-ray spectrum is featureless, and...
Guisan, J. M., Sabuquillo, P., Fernandez-Lafuente, R., Fernandez-Lorente, G., Mateo, C., Halling, P. J., ...
A novel method to prepare immobilized lipases derivatives is hereby proposed. Lipases are firstly adsorbed on supports having large internal surfaces covered by hydrophobic groups (e.g. polyacrylic...

Hiraga, J., Tsunemi, H., Miyata, E.
When an X-ray photon lands into a pixel (event pixel), the primary charge is mainly collected into the event pixel. If the X-ray landing position is sufficiently close to the pixel boundary, the...
Spectroscopic Study of the Vela-Shrapnel (1999)
Tsunemi, H., Miyata, E., Aschenbach, B.
Several shrapnels have been detected in the vicinity of Vela SNR by the ROSAT all-sky survey. We present here the spectral properties of shrapnel `A' observed with the ASCA satellite. A prominent...
