 Fri Jul 2 19:57:12 2021, Shahab, Yuri, Wolfram, Liliana, Runs, stop DAQ
|
At 19:56 the DAQ is stopped.
The plan is to go back to the setting for Se.
Last files for the Br setting:
- 410MHz-2021.07.02.19.57.36.721.tiq
-245MHz-2021.07.02.19.58.03.216.tiq |

Thu May 6 14:30:23 2021, W. Korten, General, Target thickness
|
Thickness of the Carbon target in the TE line has been measured by centering the primary 78Kr beam in the ESR:
Beam energy 370 MeV/u, with thin stripper, ESR energy 368.65 MeV
Adjust beam with "thick" target to keep ESR energy at 368.65 MeV/u -> Beam energy 445 MeV/u
Energy loss 75+1.35=76.35 MeV
Target thickness : 9.97 mm |

Thu May 6 17:48:48 2021, W. Korten, Helmut, General, ESR setting for 72Ge ions with primary beam
|
Setting the 78Kr (after the target) to the Brho of the 72Ge beam at 368.4 MeV/u (gamma=1.3955), i.e. 6.79575 Tm, which leads to an energy of 392.93 (of 78Kr).
With the 10mm Be target the beam energy should then be 467.8 MeV/u .
Yes, with my slightly different target thickenss 467.5 MeV/u (Helmut).
For 72Ge at this Brho after the target it then needs 440.95 MeV/u.

Fri May 7 03:33:11 2021, Liliana, Akash, Wolfram, Helmut, Shahab, General, status
|
At the moment we see a second peak to the left of each intense line.
The distance between the main peak and the shadow is roughly the same for each peak.
This hints to a sharp fall in the isochronicity curve.
Helmut now tries to remove these shadows by using different scrappers. |

Fri May 7 03:46:58 2021, Liliana, Akash, Wolfram, Helmut, Shahab, General, Scraper settings
|
Scraper settings have been played around with to try and remove satellite lines...
Helmut has now set scraper id GE01DS_H at -45mm (in position)
Image of injection structure attached... 72Ge is the isotope in focus on the RSA |
|
Fri May 7 07:52:12 2021, Ragan, Andrew, General, To change trigger position
|
Xiangcheng suggested to change the trigger position in order to start the file with the injection. Nothing is changed at the moment. Maybe Shahab or Yuri can do it when they arrive. |
|
Fri May 7 08:55:33 2021, Ragan, Andrew, Yuri, General, Trigger changed
|
Trigger for both the spectrum analyzers is changed from 50% to 1% by Yuri.
For this, the ESR pattern was stopped at 08:50 and was started back at 08:53. |
|
Fri May 7 09:36:32 2021, Ragan, Andrew, Yuri, General, Beam stop at 0928, adjust scope
|
It was requested from the SIS to stop the beam at 09:28
Yuri is adjusting the scope in order to avoid UFO (unidentified frequency object) |
|
Fri May 7 11:40:20 2021, Ragan, Andrew, Yuri, General, Scraper is fixed - optimisation stage
|
Scraper is fixed, we start again. Scraper open to let everything through |
|
Fri May 7 12:37:35 2021, Ragan, Andrew, Yuri, Alex, General, Back with beam
|
We are back with the beam in the ESR since 12:30
ALL SCRAPERS ARE IN THE ORIGINAL POSITIONS
E02DS3HG = - 35 mm
EEXDS2HA = - 25 mm
EEXDS1HA = - 25 mm
E01DS_H = - 40 mm
For E02DS3HG a reset in the control system needed to be done. |

Fri May 7 22:48:33 2021, Chris, General, still running...

In anticipation of the imminent shift change, a snapshot of how things look. |

|
The signal of the transformer on the lower right panel is not really beam related. It is mostly noise. Changes are not so expected with this low beam intensity |
|
Sat May 8 07:14:00 2021, Akash, Nic, Jelena, Zsolt, General, Morning shift entry
|
Things look ok. No settings have been changed...
Analysis attempts are going on... |
|
Sat May 8 07:34:08 2021, Akash, Nic, Jelena, Zsolt, General, Zoom has its own mind
|
Zoom kicked us all out... we managed to get back in...screen sharing is back on. |
|
Sat May 8 08:12:02 2021, Akash, Nic, Jelena, Zsolt, General, SIS, ESR time structure changes
|
The structure of SIS extraction seems to have changed a little...also for ESR injection.
In the span of a few minutes both the structures changed again...to look more like in the previous shifts, with lesser or no negative component. |
|
Sat May 8 15:18:23 2021, Michael, Wolfram, Yuri, General, Beam Settings changing
|
Beam settings are being changed back to 78Kr beam at 467 Mev/u. |

Sun May 9 06:53:20 2021, Iris, Chris G., Jacobus, Michele, General, Summary night shift
|
The tune last night was unfortunately not to 52Mn. The two "isomers" that were identified are instead 45Sc and 75Br. But separation looks okay. ESR morning shift should try to tune to 52Mn to identify the 21-min isomer at 378 keV.
Uploaded some pictures to prove that we were not asleep :-) but they are of limited use...at least my analyzer script and wget works now !! |
