The Swift X-ray Telescope
The Swift Gamma-Ray Explorer is designed to make prompt multiwavelength observations of Gamma-Ray Bursts (GRBs) and GRB afterglows. The X-ray Telescope (XRT) enables Swift to determine GRB positions with a few arcseconds accuracy within 100 seconds of the burst onset. The XRT utilizes a mirror set built for JET-X and an XMM-Newton/EPIC MOS CCD detector to provide a sensitive broad-band (0.2-10 ...
متن کاملEnergetic X-ray Imaging Survey Telescope (EXIST)
We have begun to study a mission to carry out the rst high sensitivity imaging survey of the entire sky at hard x-ray energies (5-600 keV). The Energetic X-ray Imaging Survey Telescope (EXIST) would include 2-4 large area coded aperture telescopes with o set elds of view allowing total exposures of > 500 ksec and ux sensitivities below 1 mCrab over the full sky in a year with time resolution fr...
متن کاملSMART-X, “Square Meter, Arcsecond Resolution X-ray Telescope”
SMART-X is a mission concept for a 2.3 m2 e ective area, 0.5 ′′ angular resolution X-ray telescope, with 5 ′ FOV, 1 ′′ pixel size microcalorimeter, 22 ′ FOV imager, and high-throughput gratings.
متن کاملX ? Ray Photon Spectroscopy with the Yohkoh Soft X ? Ray Telescope
Individual X ? ray photons in the keV energy range produce hundreds of photoelectrons in a single pixel of a CCD array detector. The number of photoelectrons produced is a linear function of the photon energy, allowing the measurement of spectral information with an imaging detector system. The Yohkoh Soft X ? ray Telescope uses a CCD in an integrating mode and makes temperature estimates from ...
متن کاملStatistical Study of Solar X-Ray Jets Observed with the Yohkoh Soft X-Ray Telescope
We have found 100 X-ray jets in the database of full Sun images taken with the Soft X-ray Telescope (SXT) aboard Yohkoh during the period from 1991 November through 1992 April. A statistical study for these jets results in the following characteristics: 1) Most are associated with small flares (microflaressubflares) at their footpoints. 2) The lengths lie in the range of a few x 10-4 x 10 km. 3...
