Energy signals of 90 and 145 degree detector have been checked and exchanged
They were connected to the wrong ADC channel.

Now 
E_Xray2 and t_Xray2 should belong to 90 degree
E_Xray3 and t_Xray3 belong to 145 degree

  152   Sat Mar 21 23:12:38 2020 JanDetectorsremoved BaF detectors 
After run 67 and before run 68, the BaF detectors have been removed in order to reduce the Compton background in the x-ray detectors.
  153   Sat Mar 21 23:19:14 2020 JanAnalysis118Te52+ on H2-target - Xray spectrum 90 degree 
The attached spectrum is for the 90 degree X-ray detector taken for about 3 hours with 118Te52+.
We see two peaks at ~29 keV (K-alpha) and 44 keV (K-REC).

The resolution is about 1.5 keV, and the signal-to-background ratio is also really bad.

The increase of background events at higher E might be induced by Compton scattering of a high E gamma ray from the BaF detectors, which are active and sit close by (not anymore).

  159   Sun Mar 22 01:36:14 2020 Pierre-MichelAnalysisTarget overlap 
Here are the data file for the rates of the recoil detector for different values of the target bump. The average rate over background is proportional to the target overlap. 

The MCP was operated at a voltage of 2500 V, where it sees mostly photons, so not really recoil ions.

Column "X" is time in seconds, Column "Content" is rate in Hz.
