Louis | OFFLINE | General | CD2 | Offline analyis run 53 |
1) Some angular distribution were extracted (without any efficiency corrections) with gate on Ex btw 0 and 2 MeV (where p orbitals are populated) and btw 2 and 4 MeV (where f orbitals are populated). More counts are observed btw 110 and 120 degrees in Lab angle with the 0-2MeV gate compared to the 2-4MeV gate which is expected from the AWBA calculus. Kinematic cuts the large angles at high excitation energies. Geometrical efficiency is needed to compare this angular range. Looks like we well distinguish L=1 and L=3 transfers.
2) Some gamma spectra obtained with Ex gate btw -1 and 1, 1 and 3, 3 and 5 MeV.
3) Some strange horizontal lines are observed in the E-TOF id in MUST2. The spectra was obtained with gate on the promt signal in vamos so it can not be the beam intercepting directly must2...
4) the Ex vs Eg matrix |

Ablaihan, Louis | BEAM | General | CD2 | VAMOS transmition |
| at 2h50 beam intensity reached 1.1x10^6 pps in CATS for 6.5x10^5 pps in VAMOS. The transmition decreased to 60% without any shift of the beam position. Does it come from a loss of efficiency of VAMOS at high counting rate? |

Adrien, Freddy, Wilton and Nigel | OFFLINE | General | CD2 | Offline analysis of run 51 and 52 using ganil files |
We noted that the gamma ray efficiency calculated from file converted from AGATA was close 100%. We concluded that the conversion program was reauiring a gamma ray to be present.
This is confirm by analysis of the ganil dta file that show 10 time more count that the agata one.
Here is a kinematical plot of the run 51 and 52 analysised from ganil file.
There is a 1.5MeV state present that disappear in the agata coincidence. This is to be investigated with more data. Is it an isomer state? from 48K? 48Ti? |

mugast (Adrien, Nigel et co) | BEAM | General | | Primary beam issues |
The secondary beam intensity has been fluctuating around 4 - 5 x 10**5 Hz most of the evening. 15 mins ago it was realised that it had dropped off to only 1 x 10**5 Hz. As suspected, PCP confirmed that primary beam intensity has dropped off. They are investigating ...
It would be good to have the TI (primary beam intensity) available to monitor here in the daq room. |

Nigel | BEAM | General | CD2 | Beam centering - MUST2 hit pattern |
We made a quick check of the beam centering by inspecting the MUST2 (forward angles) hit pattern (plot attached). It appears that the beam is probably somewhat off centre in the horizontal direction.
It has been decided to run overnight like this and then see with Bertrand if the centering can be improved (will need to send hit pattern spectrum to PCP in order for Bertam to do this).

Charlie | OTHER | General | | 48Ti Kinematics (additional) |
Supplementary to Adrien's kinematic calculations of 47Ti(d,p)48Ti, we have found a paper suggesting that by far the most strongly populated state in 48Ti is at 5.65 MeV. There is also a doublet of strong states at around 4.4 MeV, and two more strongly populated states at 6.06 and 6.33 MeV.
See attachment for the full table from P. D. Barnes (1965), Phys.Rev.138.B597.
Some quick CatKin models also show that a (theoretical) state at 7 MeV in 48Ti would almost perfectly overlap with the ground state of 48K. As such, when looking at the lab energy with the g.s. of 48K normalised to 0, we could expect to see these strongly populated 48Ti states at -0.67, -0.94, -1.35 and -2.6 MeV (for 6.3, 6.06, 5.65 and 4.4 MeV, respectively).
See the attached plot for kinematics of 47K(d,p)48K @ 0 MeV and 4 MeV, as well as 47Ti(d,p)48Ti @ 0 MeV, 5.65 MeV and the theoretical 7 MeV. Additionally, see a mock-up of the expected spectra from Wilton. |
