Sat May 10 00:52:21 2025, Finn, Simon, Konstantin, Rodolfo, DAQ, Bunching - ammendment late shift
|
Some 209Bi80+ beam was provided for tests measurement over the weekend. Currently the beam is bunched at the second harmonic, corresponding to a bunching
frequency of [B]3.87421MHz[/B] and a revolution frequency of [B]1.937105MHz[/B]. The setting of the rate dividers were 2 and 99. Two is important since
we are working with the second harmonic, and 99 provides approximately 20kHz, which is expected by the DAQ. The measurement of the frequency was performed |
|
Sat May 10 03:32:18 2025, Finn, Simon, General, Beam not bunched (?)
|
We think the beam in the ESR is not bunched. There is a clear difference in PMT signal if ions are in the ESR compared to no ions (see screenshot of scaler
PMT mid, high level with ions, low level without) but we see no structure of an ion bunch (see screenshot of accumulated bins).
We also increased the accumulation to 10 injections, still no bunch visible.
|
|
Sat May 10 03:46:57 2025, Finn, Simon, Detectors, PMT north
|
In contrast to PMT Mid, the difference between ions and no ions in the ESR (see screenshot scaler) is not visible. Signal gets higher with injection and
shows some kind of exponential decay afterwards.
Beam was dumped at 500 and 1200s. Even after the dump, the signal steadily drops.
|
|
Sat May 10 03:54:46 2025, Finn, Simon, Carsten , General, Night shift sum up - ammendment day shift
|
As the beam in the ESR is most probably not bunched, there was not much we could do. During the night shift we:
- adjusted the threshold of the PMTs mid and north with beam in the ring
- found that the delay generator for PMT mid is broken, so the timing is off and needs to be remeasured
|

I tried scraping with pressurized-air devices in order to verify the beam poistion. All 4 devices that we use do not work reliable (at least when driven

The ion pumps (E02VP16i and E02VP17i) which nearby the optical detection region produce high count rate into the photomultipiers. Therefore they were turned
off on May 5th by our colleague from UHV (Herr Mia). He checked the vacuum before (EIN) and after (AUS) turning off the pumps. |

also a tiny indication on PMT north (att. 1 left).
On the particle detector, the bunches are clearly visible (att. 2).

We changed the position of the laser back to the position which was set up in [COLOR=blue][B][URL=https://elog.gsi.de/esr/E0038/85]E 85[/URL][/B][/COLOR]
by changing the motor position of motor 4 in the kangoo software at ATPPC031 from -0.1 to -0.3. |

Tue May 27 10:56:44 2025, Konstantin, DAQ, Common stop
|
The common stop was wired through a 1:2, and subsequently through a 1:99 rate divider channel. However, since the pulse width was too long, the 1:2 channel
was translated into a 1:4 reduction. This must be considered, when the data is processed via go4. The reduction factor in the SetParameters.C file must
be set to 198 accordingly. |
