Visible Light Diagnostics and Streak Cameras
General description :
The UV and visible light is extracted from the upstream dipole of Cell 5 and directed to a dedicated laboratory of ~20 square meters that is permanently accessible. It accomodates an optical table, at 8.5m from dipole source point, that supports the components of independent systems like the Visible Light Beamspot Monitor, the StreakCamera, and Ultra-Fast-Photo-diodes.
The light extraction mirror, in UHV at 3.2m from the dipole source point, avoids the surface deformation from the extreme X-ray power in the beam by operating as a ‘half-mirror’ i.e. only the top part out of the vertical light emission cone is extracted with the powerfull heart of the beam just going underneath the mirror edge.
