 Sun Mar 15 17:13:21 2020, Laszlo, Jan, Calibration, the x-ray gate issue, 
|
We found a strange behaviour of our ADC gates for the x-ray detectors.
The setting as shown in the foto below corresponds to a delay of 5 us and a gate length of 15 us.
This is the only setting that produces nice spectra, even though the signals and gate are not aligned.

|
We are now using new SpecAmps for the x-ray detectors from ORTEC, they deliver much improved resolution but have other strange effects as discribed in the
next entry. |

Tue Mar 10 09:41:26 2020, Jan, Detectors, x-ray background from BaF,
|
The BaF2 detectors planned to be installed at the target induce an additional background in the x-ray detectors sitting below inside the target chamber.
We made test measurements with an x-ray detector for estimating the background in the region of interest for our K-REC measurements (35 to 50 keV).
