Shumpei | OFFLINE | General | Cryo-LH2 | 37Ca (p,d) 36Ca |
37Ca (p,d) 36Ca reaction is analyzed (run 191-195).
Gate condition;
1. beam on target by CATS1&2
2. TOF gate for 37Ca
3. recoil deutron gate by MUST2 only T3
4. fragment gate by CHIO and plastic
Only T3 is used for analysis and the angle is intentionally shifted 1.0 deg to match the kinematics for 40Ca (p,d).
Ground and 2+ state of 36Ca are observed in Z=20 gate, while a higher lying state is seen in Z=19 gate.
This result seems to be consistent with that of 38Ca (p,t) 36Ca. |

Nori | BEAM | General | N/A | Brho1 and Brho2 optimization for 37Ca |
Summary of Brho1 and Brho2 optimizations for the 37Ca beam.
Attachment 1:
Results of the Brho1 scan. Corresponding LISE run numbers are also shown in the figure.
As the beam intensity was fluctuating, the counting rates were normalized with respect to the intensity.
By changing Brho1, we tried to search for the peak of the 37Ca production. The yield seemed to reach the maximum at around 2.10 Tm,
although sometimes the rates were not reproducible (see the data point of the run 306, for example).
Attachment 2, 3:
Changes of the yield and purity by scanning Brho2. The shaded area corresponds to the width of the slit (shown only for 0%).
They were well optimized at about 1.925 Tm. |

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 |
