We were searching for a difference of a factor of twoin both DAQs. It turns out that the default value for the MBSstream server task is scale=2. In the main task this value is explicately set to scale=1. we will now (starting with filenumber: 0078) restart the 2nd DAQ with set stream_serv scale=1.
Also TDC is disabled.
From file number 0076 in DAQ2 : ADC thresholds:

Before the next scan, we realized, that the laser destabilized. For the rest of the shift we tried to get laser back online (see ID:149). |
