 Thu May 6 21:45:30 2021, Helmut, Detectors, beam position on TE5 grids 
|
The two grids do not work very well, one x position is opposite to the other.
But at least a guidance for the future, this was good injection of 78Kr with a thick Be target. |

|
NTCAP was stopped at 17:34 for the optimisation purpose.
NTCAP started again at 18:20 with the change in Reference Level (dBm): 0

Fri May 7 01:49:03 2021, Rui-Jiu Chen, DAQ, Comparison of I_Raw/Q_Raw between different reference level
|
This is a comparison of I_Raw/Q_Raw between different reference level. The range of NTCAP ADC is only 2^15 bit. So signals (I_Raw and Q_Raw) should
not be outside ADC range. It is clear that there is not point outside the ADC range when using reference level -30dBm. |
