5Performance evaluation of an SOI pixel sensor with in-pixel binary counters显示文摘Introduction Pixel detectors fabricated with the silicon-on-insulator(SOI)technology suffered from the digital pickup,due to the capacitive coupling between the sensing electrode and the in-pixel circuit.In order to tackle this issue,an advanced process called double SOI has been developed.A prototype chip CPIXTEG3b adopting this new process was designed and characterized.While optimization concerning the double-SOI design and testing of the single pixel were already presented in a separate publication,this paper focuses on its noise performance of the full matrix and X-ray detection utilizing a synchrotron photon beam.Methods Equivalent noise charge(ENC)of the full pixel matrix was measured with electrical pulse tests.The threshold dispersion was minimized by the DAC tuning in each individual pixel.As a photon-counting X-ray imager,noise count accumulated up to 1 h was measured.Detection efficiency was measured with a micro-focused beam as well as a flat field generated by the X-ray scattering on a glassy carbon at the KEK PF beam line 14A.Results The typical ENC is 52 e−and the sigma of threshold dispersion is 10 e−over the full matrix.A merit of“zero”noise count is also demonstrated,which is consistent with the low ENC.The prototype chip has been tested with microbeam and used to measure the beam profile to be with a full width of 50µm at 2.4%of the maximum height.Both sensor depletion and charge sharing between neighboring pixels have been carefully characterized,providing insights for further development.The homogeneity of response to X-ray photons has been demonstrated in the flat field test.This work has drawn a final conclusion to the solution of digital pickup issue and opened a promising prospect in low-noise and high-resolution X-ray imaging.Longlong Song Yunpeng Lu Ryo Hashimoto Ryutaro Nishimura Shunji Kishimoto Yang Zhou Zhigang Wu Yasuo Arai Qun Ouyang 2018Radiation Detection Technology and Methods2018,2,1:0
6Near-infrared polarimetry of the GG Tauri A binary system显示文摘A high angular resolution near-infrared image that shows the intensity of polarization for the GG Tau A binary system was obtained with the Subaru Telescope.The image shows a circumbinary disk scattering the light from the central binary. The azimuthal profile of the intensity of polarization for the circumbinary disk is roughly reproduced by a simple disk model with the Henyey-Greenstein phase function and the Rayleigh function, indicating there are small dust grains at the surface of the disk.Combined with a previous observation of the circumbinary disk, our image indicates that the gap structure in the circumbinary disk orbits counterclockwise, but material in the disk orbits clockwise. We propose that there is a shadow caused by material located between the central binary and the circumbinary disk. The separations and position angles of the stellar components of the binary in the past 20 yr are consistent with the binary orbit with a = 33.4 AU and e = 0.34.Yoichi Itoh Yumiko Oasa Tomoyuki Kudo Nobuhiko Kusakabe Jun Hashimoto Lyu Abe Wolfgang Brandner Timothy D.Brandt Joseph C.Carson Sebastian Egner Markus Feldt Carol A.Grady Olivier Guyon Yutaka Hayano Masahiko Hayashi Saeko S.Hayashi Thomas Henning Klaus W.Hodapp Miki Ishii Masanori Iye Markus Janson Ryo Kandori Gillian R.Knapp Masayuki Kuzuhara Jungmi Kwon Taro Matsuo Michael W.McElwain Shoken Miyama Jun-Ichi Morino Amaya Moro-Martin Tetsuo Nishimura Tae-Soo Pyo Eugene Serabyn Takuya Suenaga Hiroshi Suto Ryuji Suzuki Yasuhiro H.Takahashi Naruhisa Takato Hiroshi Terada Christian Thalmann Daigo Tomono Edwin L.Turner Makoto Watanabe John Wisniewski Toru Yamada Satoshi Mayama Thayne Currie Hideki Takami Tomonori Usuda Motohide Tamura 2014Research in Astronomy and Astrophysics2014,14,11:0
