Description
A commercial scientific camera has been bought by the SOLEIL Synchrotron for improving the acquisition capabilities of the soft X-ray coherent scattering experimental station at SEXTANTS beamline. The device is equipped with a commercial Back-Side-Illuminated scientific CMOS (BSI-sCMOS) developed by Gpixel Inc. It has a sensitive area of $\sim 2 \times 2~\rm{cm}^2$ for a pixel pitch of $11~\mu\rm{m}$ and a frame rate of 48 Hz for a low noise image. The sensor has different working modes, which provides a low read-out noise (1.6 $\rm{e}^-$ R.M.S in High Gain mode) and a large full-well capacity ($\sim 80~\rm{ke}^-$ in Low Gain mode).
For being able to work in vacuum conditions, the camera has been adapted and tests results obtained in laboratory will be presented.Moreover, an overview of beam-time campaigns at the soft X-ray branch of the METROLOGIE beamline will be given. The radiation hardness of the chip has been quantify, as well as its Line-Spread-Function (LSF) and Modulation Transfer Function (MTF). Further tests are foreseen with this imager on SEXTANTS or HERMES beamline.
