54 54  The idea is, that the crystal can be used for tuning and looking at the beam profile but **NOT as beamblock** (which is now a separate device). In order to avoid too much moving in and out of the crystal, there is a button (in the red warning box) which resets the timer. If the button is pressed the time window starts again and the crystal stays in ...
