Subject: CATS scaler not compatible with beam rate 
The CATS scaler si now around 100-120 kHz while the beam rate is still 40 kHz.

I checked the CATS signal and there is clearly noise who induce double logic signals. Not all of them are validated by FAG.

We should raise the threshold- call sebastien

9h32 : Stop beam to enter and raise the threshold.
