Dark room

  The visible and UV synchrotron light is separated from the X-ray photon beam by an in-vacuum mirror installed in the optics hutch and is transported in the bent shielded pipe to the dark room on the experiment hall. The visible light is used for diagnostics of longitudinal properties of the storage ring beam, such as bunch length and bunch purity. Bunch length is measured by a streak camera. Bunch impurity is measured by the bunch purity monitor.
