    Dr Hirokazu Odaka (ISAS/JAXA)
    27/08/2015, 15:50
    An astrophysical system harboring a strong gravity star such as a black hole or a neutron star accretes gas from the circumstellar environment, releasing enormous gravitational energy via accretion onto the deep potential. Since a large fraction of the accretion power is released in a form of X-ray radiation, X-ray spectral and temporal information is an important probe to study the energetic...

  19. 2. In-orbit Performance Estimation of the Hard X-ray Imager onboard ASTRO-H with Monte Carlo simulations
    Kouichi Hagino (ISAS/JAXA)
    27/08/2015, 16:15
    The Hard X-ray Imager (HXI) is one of four instruments onboard 6th Japanese X-ray satellite, ASTRO-H, which is scheduled to be launched in FY 2015. Combined with hard X- ray telescopes, the HXI will realize imaging spectroscopy in hard X-ray band ranging from 5 keV to 80 keV with a sensitivity which is two orders of magnitude better than that of Suzaku/HXD. The HXI is composed of a stacked...

    Dr Masanori Ohno (Hiroshima University)
    27/08/2015, 16:40
    The Hard X-ray Imager (HXI) and the Soft Gamma-ray Detector (SGD), onboard instruments of Japanese 6th X-ray observatory, ASTRO-H, are surrounded by the large number of BGO (Bi$_4$Ge$_3$O$_{12}$) scintillators for active shielding. These active shields are very important to reduce the non X-ray background such as cosmic rays and/or gamma-rays from radioisotopes produced by activation of the...

  21. 1. The localizing algorithm of gamma-ray bursts and evaluation of systematic error in Suzaku Wide-band All-sky Monitor using Geant4
    Takeshi Fujinuma (Saitama University)
    27/08/2015, 17:05
    The Wide-band All-sky Monitor (WAM) on board the X-ray astronomical satellite Suzaku consists of four sides of BGO scintillation counters within the Hard X-ray Detector. Thanks to large effective area (800 cm2 at 100 keV) and field of view of ∼ 2π st, the WAM has detected transient objects, such as Gamma-Ray Bursts (GRBs) and Solar flares, approximately 300 event per year. However, the WAM...

  27. 14. Evaluation and Application of U.S. Medical Proton Facilities for Single Event Effects Test
    Prof. Robert Reed (Vanderbilt University)
    28/08/2015, 11:35
    The sudden closure of the Indiana University Cyclotron Facility (IUCF) has forced the space community to evaluate alternate medical proton cancer therapy center cyclotrons for single event effects (SEE) test in the 200 MeV regime. These new facilities offer increased reliability well adapted to medical needs, but create scheduling and technical challenges for those adapted to IUCF. A team of...

    Ngoc Hoang Tran (Division of Nuclear Physics, Ton Duc Thang University, Tan Phong Ward, District 7, Ho Chi Minh City, Vietnam.)
    28/08/2015, 14:25
    Gold nanoparticles have been reported as possible radio-sensitizer agents in tumor radiation therapy, in particular through the increase of local energy deposition in close vicinity of the nanoparticles and subsequent direct damage to cells and DNA. Moreover, indirect damage originating from the increased production of chemical species induced by such additional energy deposition events around...
