Thu May 27 13:26:35 2021, Jan, Accelerator, FRS degrader failure, 2021
|
Maybe, our degrader in FRS was removed by hand at (~13:40 26/05/21)
It is put back now (~13:10 27/05/21)
All runs taken in this period have to be double checked!

Thu May 27 13:48:18 2021, Helmut Weick, Accelerator, FRS wrong status display for one day, 2021 
|
By checking the log files we realized that from yesterday 26.05. 13:44 - today 13:05 the FRS degrader was shown as out.
TS3ET7US should be at -420.0mm not at -580mm (=out). This 3.26mm Sci is used as a degrader and is essential.

Fri Aug 9 13:14:09 2019, Laszlo, , pn channel simulations for 111Sn(p,g)112Sb experiment,
|
The p,n channel opening for the 111Sn+p reaction is at 5.8895 MeV/u beam energy. Therefore, when choosing as 6MeV/u, 7MeV/u, 8MeV/u beam energies, there
is not much kinetic energy left for the outgoing neutron --> there are "less" nuclear levels populated above groundstate in 111Sb, they can be handled
explicitly. My simulations are based on TALYS results. The following steps did I made:
|
|
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...)
|
|
Sat Mar 21 13:37:53 2020, Laszlo, , MCP can monitor target,
|
now with the MCP we can see clearly the effect of the target :) (scintillation?)
so we want to scan through the target thickness with the beam and choose the best position afterwards.

Sun Mar 22 17:47:27 2020, Laszlo, , Si, Xrays target density spectra during 118Te afternoon measurement,
|
We got 30 counts out of this afternoon 118Te run on our Si TargetON histo.
That 1 count at bin (6,10) I dont understand.
|
|
Sun Mar 22 18:35:43 2020, Laszlo, , target dropped aagain,
|
| there was a drop again from 8.6e13 to 7e13 in the target density |
|
Sun Mar 22 19:15:03 2020, Laszlo, , Si moved out of the ring, high voltage is switched off,
|

|
Sun Mar 22 19:49:12 2020, Michael, Laszlo, Yuri, , Yuri is still tuning FRS,
|
We filled the Xray detectors.
Yuri is sill tuning FRS for primary beam. |
