Fiber Optics for Zeff measurement

To measure intensity of visible bremsstrahlung for determination of Zeff

[Detectors, Diagnostic Method]
Light collected by a lens is transmitted by optical fibers from the torus hall to a diagnostic room.

The light from the optical fibers passes an interference filter and is detected with a photomultiplier.
