Kseniia, Franck | ONLINE | General | LiF | Run 149 screenshots |
A second beam component is visible in particular in IC energy losses (with Z larger than 7) and in MW.
This probably corresponds to the 15O from the Spiral target-ion source being warmed up by the primary beam that has increased overnight (~1200 W at 5:45 am).
Checked by reducing the primary intensity for a few minutes: the second component decreased to a level comparable to that at the beginning of run 149. |

Kseniia | AGATA | General | | 15O implantation |
Attached is the intensity distribution of 511 keV in run 119 (first image) vs run 120 (second image).
In between the two runs, beam optics was twitched.
These are the segments of crystal 02A which is near the beam pipe. Bottom is the tip of the detector, top is the
tail.
In run 119 it looks that the pillars that are near the beam line (columns 4 and 5) were seeing 511 more or less
homogeneously, which means that we are implanting 15O all over the pipe.
In run 120 looks like we still implant in the pipe, but also we implant a lot more at the target level. |

Juan Lois & faïrouz & Adrien | BEAM | Hardware | CD2 | Beam intensity escalated up to 1.6e6 pps |
At 9:57 the intensity increased up to 1.6e6 pps and we had to call the pcp to put it again to the normal values.
It was solved by 10:07 .
Same incidence happend at 10:17 and then again at 10h30.
The beam operators close little bit the slits to decrease the beam intensity.
The intensity is now 3.e5 pps |

Jenn, Kseniia | OTHER | General | | Overview nightshift run 112 |
Smooth night, everything was working properly.
Checked agata rootfile to see preliminary gammas.
19Ne 275 state observed
Also 19F (strong 109 state) (fusion-evaporation?)
Check Agata elog for more details. |
