The webline (arrow) in the control room of linac Green. (Note the fairly new 5-camera Video surveillance system.)
We especially learned to appreciate the automatic stop-and-restart-function, which even works perfectly with dose rates of 1000MU/min.
When not in use, the webline is in Standby mode, which keeps all electronics under thermal equilibrium. After power up, the dosemeter immediately gives stable readings.
Of course, the webline is "eichfähig".
