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...)

|
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

Sat Mar 21 12:06:50 2020, Laszlo, General, run61 - SCRAPER moved out,
|
| we want to see any change on the Silicon count rate, because we will have now also Rutherford scattering. |

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?

Sat Mar 21 12:42:21 2020, Ragan, General, Entry to ESR for MCP detector,
|
Pierre Michel and Laszlo go inside the ESR for switching on the MCP detector so that the photons from the gas jet and secondary beam interaction can be
seen.
