Electron-multiplying CCDs for future soft X-ray spectrometers
CCDs have been used in several high resolution soft X-ray spectrometers for both space and terrestrial applications such as the Reflection Grating Spectrometer on XMM-Newton and the Super Advanced X-ray Emission Spectrometer at the Paul Scherrer Institut in Switzerland. However, with their ability to use multiplication gain to amplify signal and suppress readout noise, EM-CCDs are being conside...
متن کاملOn the use of electron-multiplying CCDs for astronomical spectroscopy
Conventional CCD detectors have two major disadvantages: they are slow to read out and they suffer from read noise. These problems combine to make high-speed spectroscopy of faint targets the most demanding of astronomical observations. It is possible to overcome these weaknesses by using electron-multiplying CCDs (EMCCDs). EMCCDs are conventional frame-transfer CCDs, but with an extended seria...
متن کاملDeveloping a high-resolution x-ray imager using electron-multiplying (EM) CCDs
Applications at synchrotron facilities such as macromolecular crystallography and high energy X-ray diffraction require high resolution imaging detectors with high dynamic range and large surface area. Current systems can be split into two main categories: hybrid pixel detectors and scintillator-coupled Charge-Coupled Devices (CCDs). Whilst both have limitations, CCD-based systems (coupled to f...
متن کاملElectron mobility in Si delta doped GaAs
We have measured the transport and quantum mobility in Si delta doped samples as a function of the doping concentration and the thickness of the doping layer. The results are compared with mobility calculations which show that the ionized impurity scattering rate is determined by the fluctuations in the charge distribution of the delta layer instead of the full charge distribution itself.
متن کاملA study of Electron-Multiplying CCDs for use on the International X-ray Observatory Off-Plane X-ray Grating Spectrometer
CCDs are regularly used as imaging and spectroscopic devices on space telescopes at X-ray energies due to their high quantum efficiency and linearity across the energy range. The International X-ray Observatory’s X-ray Grating Spectrometer will also look to make use of these devices across the energy band of 0.3 keV to 1 keV. At these energies, when photon counting, the charge generated in the ...
