Jan exchanged the Mesytec CFD/shper since it could not be "remote controlled" anymore. The new one has different shaping times and delays.
It is noted the threshold range is rather small. 
With the new  shaper only the x100 signals could meaningfully discriminated etc.
After start of the ESR (magnets etc.) the signals of the 10x channels see quite some noise that makes it more difficult to adjust the thresholds for the low signals.
