Fixed, e755, Sat Jun 30 23:47:45 2018, takeshi, daisuke, didier, BEAM, General, Cryo-LH2, result of Wien filter tuning
|
Here is the summary of the tuning of the Wien filter.
We tried to tune the correction magnet of the wien filter to change the Y position of the beam, especially for 37Ca, which seemed to be at slightly higher position.
The peak position was shifted lower and lower and the purity of 37Ca was increased as changing the magnetic field of the wien filter with decreasing total beam rate.
The rate of 37Ca was actually not changed by the tuning of the wien filter and 36K was decreased by this tuning, although the rate of 35Ar, which are not interest nuclide for us, was decreased significantly.
The dead time of DAQ is not so serious in current setting, so we decided to continue the measurement without changing the wien filter. |

Update of offline Analysis of the 37Ca(p,d)36Ca reaction:
Run 192 to 207
Total time: 43h
same analysis for gate Z=20, Z=19 and Z=18 have been made.
In the first exited state at 5.5MeV of Z20 spectra we got 1557 counts ==> 36/h
in pic of Z19 spectra we got : 121 counts at 5.5MeV ==> 2.8/h
458 counts at 9.8MeV ==> 10.5/h
for the first excited state at 5.5MeV we got gamma to proton ratio of 7.7%
One can maybe distinguish resonnace in the Z18 spectra |
