Jan | Analysis | 118Te52+ 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). |

Jan | Detectors | removed 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. |

Laszlo, Jan | DAQ | changing cables of the Xray 90 and 145 | |
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 |

Jan | Runs | target incident | |
in run 66 or 67 we had a single ESR cycle for which the target didn't switch off for new injection and deceleration etc.
Very likely the DAQ also didn't get an OFF signal and collected OFF data to the TRIGGER=1 (ON data) branch.
As a consequence we collected about ~100 counts on the Si in one shot, which was about ~20 counts before this shot.
