This section gives a quick visual indication on whether or not there is beam in the hutch. If any of the two indicators are red, you won't have beam on the sample.

• Beam Dumped: This queries whether or not there is light on the monochromator. Red means no light, green means beam on. The status depends on the current on IMonoIn. It can happen that this value is below a threshold value if the storage ring runs at a reduced current. If this is the case, the system thinks you have no beam and won't allow you to do any tuning, although there might be sufficient beam on the mono. Call the beamline staff if you suspect this is the case.
