Tangential Fiber Array 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 interference filters and are detected
