Development of Thick-foil and Fine-pitch GEMs with a Laser Etching Technique (2009)
Tamagawa, T., Hayato, A., Asami, F., Abe, K., Iwamoto, S., Nakamura, S., ...
We have produced thick-foil and fine-pitch gas electron multipliers (GEMs) using a laser etching technique. To improve production yield we have employed a new material, Liquid Crystal Polymer,...
Search for Sc-K line emission from RX J0852.0--4622 Supernova remnant with Suzaku (2009)
Hiraga, Junko S., Kobayashi, Y., Tamagawa, T., Hayato, A., Bamba, A., Terada, Y., ...
We searched for evidence of line emission around 4keV from the northwestern rim of the supernova remnant RX J0852.0-4622 using Suzaku XIS data. Several papers have reported the detection of an...
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant (2009)
Furuzawa, A., Ueno, D., Hayato, A., Ozawa, M., Tamagawa, T., Bamba, A., ...
We use \suzaku observations to measure the spatial variation of the Fe K$\alpha$ line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a FWHM value of...
Suzaku Observations of Tycho's Supernova Remnant (2008)
Tamagawa, T., Hayato, A., Nakamura, S., Terada, Y., Bamba, A., Hiraga, J. S., ...
Tycho's supernova remnant was observed by the XIS and HXD instruments onboard the Suzaku satellite on 2006 June 26-29 for 92 ks. The spectrum up to 30 keV was well fitted with a two-component model,...
