18:30Uhr:
Timestamp im Programm hat gehangen. Kurz im Anzeigefeld markieren und es ging wieder.
Laser Step Counter hat gehangen und lag mit 4Go 20 Steps auseinander. Da es früh genug auffiel wurde der Number of Steps von 52 auf 72 erhöht. Ist also |

Fri Feb 28 19:33:03 2025, Volker, Detectors, Laser background
|
We measured the laser background rate in the XUV detector.
The voltages applied were +300V at the MCP front, +2250V at the MCP anode.
Trigger threshold at ca. 40 mV.

Der UV Monitor steht in der Reflexion des PBSC auf dem Lasertisch im Laserlabor.
P_Transmission = (1-(0.9364 * cos^2(0.0349* (theta - 33.014)) + 0.06043)) *P_Reflex

|
Hallo zusammen,
wir haben den Scan-Bereich vom Laser - bei der Ionenenergie die wir jetzt haben - nun komplett ausgenützt.

Signal of PMT-Mitte. Recorded with an unstable ion bunch. With approx. 3E8 Ions
The second screenshot is showing a similar signal with 1.8E8 Ions |

Thu Feb 6 12:54:29 2025, Danyal, Accelerator, HV-divider for electron cooler connected - readout is running
|
The HV-divider has been connected to the E-Cooler.
The readout (by Konstantin) is running too.
|
|
Thu Feb 27 09:59:08 2025, Konstantin, Calibration, HV-Divider
|
The readout of the HV divider runs on a RaspberryPi inside the HV-cave of the electron cooler.
Starting from 2025-02-27 09:42, the divider ratio was changed from 248517 to 248515. Usually, the
readout should run continuously. If not, the following procedure must be applied:

Fri Feb 28 15:53:44 2025, Konstantin, Accelerator, HF Signal for Bunching
|
The HF Bunching Frequency is: 1.7838817 MHz
Given (read) by the ESR operators in HKR. |
|
Thu Feb 27 16:30:57 2025, Konstantin und Rodolfo, DAQ, HF Signal
|
| We have exchanged the HF-Signal in the DAQ Electronic: from Dummy-HF to the real HF from accelerator. |
|
Sat Mar 1 13:45:42 2025, Konstantin , DAQ, Gentec readout
|
Gentec readout is now included in the general slow data acquisition. The issue was that the buffer of the power meter was not emptied fast enough. Now,
the data is read out permanently in a separate thread. |

Fri Feb 28 15:30:41 2025, Tamina, Rodolfo, Detectors, Fast PD Nord West
|
We had an issue with the PD NW. The signal after the Rate Divider was not OK.
The problem was that the signal after the Delay Generator GG8000, the width, was too short. We have now changed the width and made similar to the PD SW. |
