Signal stability of high-Z sensors at synchrotron light sources

D. Greiffenberg, Kirsty A. Paton, J.H. Mulvey, A. Bergamaschi et autres

Abstract The use of high-Z sensors for scientific applications at synchrotrons will gain more importance due to the upgrade of many light sources around the world to diffraction limited light sources for which the photon flux at high photon energies (above 30 …
