抄録(英)
The Gas Slit Camera (GSC) onboard MAXI consists of 12 slit cameras. Each camera utilizes slat collimator, a slit and a proportional counter (PC). The slat collimator limits the FOV into an arc of 1.5 x 80 degrees. The slit makes one-dimensional image on the PC within the FOV. The one-dimensional position-sensitive PC is filled with Xe gas. Thin carbon fibers (10 micrometer in diameter) are used as the resistive anodes, which enables position resolution of 1 mm. Six anode cells are surrounded by the veto layers, which achieve a low background rate by anti-coincidence. Six cameras are placed to cover an arc of 1.5 x 160 degrees of the forward direction, and other six cameras are to the zenith direction. The total area of the twelve PCs is 5350 sq cm. The energy range is 2-30 keV. The sensitivity of one scan is 7 mCrab (5 sigma), which reaches 1 mCrab in one week.
