Direct X-Ray imaging for the new pinhole diagnostics at BESSY II

In order to improve our transverse diagnostic tools, two new pinhole beamlines will be designed. The pinhole arrays will be in air for easier maintenance: this will result in a significant loss of X-Ray photons when passing through the vacuum window. To overcome this issue, the option to directly illuminate a CCD/CMOS camera with X-Ray radiation without prior conversion into visible light is under study. Tests in the existing beamline both with a conventional CMOS camera and with a dedicated X-Ray camera are foreseen. This report describes our findings regarding the current status regarding the use of X-Ray cameras as a "high flux" diagnostic tool, as well as our preliminary experimental results.
