Sat Mar 21 11:25:47 2020, Laszlo, , possible misalignement between target and fragment beam, 
|
after 9hours of measurement we see only 19 counts on our targetON silicon detector histo. this low count rate can indicate two scenarios:
-we have a mismatch between the beam and the target (not much if any overlap)
-mabye the very low intersity of the beam (we cannot really monitor this, there are only estimates...)
Which tells us that we dont intersect with the target, that on the Xray spectras we dont see any peaks at 90 and 145 angles. There are two peaks in 35 angle, but they are maybe only from Pb conversion 75keV, etc... |

Sat Mar 21 11:30:04 2020, Laszlo, General, MWPC movement,
|
now we try to move the capture detector (MWPC in the 1. dipol before our Si setup) inside the ring while the DAQ was ON
we tried to move it as close as possible to the beam
On the picture below you can see that we had some increased current while moving the MWPC --> scattering from the beam while scraping it |

Sat Mar 21 12:32:00 2020, Laszlo, General, Estimated target thickness,
|
Target thickness must be like 5mm (was measured with a moving thin wire)
The beam thickness is small because of the low intensity
Maybe we hit the target a bit offset --> less rate?
We might have the option to increase the target 1magnitude more, but this might not help because we can kill the beam
with this.
I have the impression we just simply have less number of stored ions like 10^4 or evem less...
