| Filters (Hepa-) inside the flow boxes have been replaced. |

Thu Apr 14 17:47:55 2022, Carsten, Rodolfo, Konstantin, Sarper, Runs, Afternoon shift runs 14.04 changing the wavelength scan range
|
The new scan range is changed from [B]321.12 - 320.60 nm to 320.62 - 320.10 nm[/B]

Mon Apr 11 14:45:11 2022, Paul, Konstantin, Sarper, David, Runs, Afternoon shift runs 11.04
|
We continue scan the new wavelength scan range is 322.41 - 322.00 nm
|
|
Sat Apr 9 15:47:21 2022, Carsten, Rodolfo, Sarper, Patrick, Runs, Afternoon and night shift runs
|
After the morning shift, we got new increment (nm) for the laser scanning. We are now scanning 2 nm of wavelength range in 5 big steps (5 x 0.4 nm). Started
with 323.2 nm - 322.8 nm range. Every big step (0.4 nm) is scanned with 0.002 nm of wavelength increment.

Wed Apr 13 14:29:04 2022, Carsten, Rodolfo, Sarper, David, Pierre-Michel, Max, Sebastian, Runs, Afternoon - morning shift runs 13.+14.04.
|
Changed the wavelength scan range from [B]321.62 - 321.10 nm[/B] to [B][B]321.12 - 320.60[/B] nm[/B] after one scan.

Wed Apr 6 15:19:29 2022, Svea, Shahab, Accelerator, 5s delay implemented before injection
|
Operators have informed us that for better stability and operation (and cooperation with HHT), and after discussing with Sergey, they have introduced 5s
delay "Wartezeit RESET" before every injection.

Tue Apr 12 04:43:29 2022, Alexandre, Kristian, Sebastian, Runs, 322.01 - 321.60 nm
|
We scan the wavelength scan range is 322.01 - 321.60 nm
before the first scan of the new wavelength range we changed the high voltage divider ratio in Labview from 248514 to 248517, which is the correct value |

Sat Apr 9 04:01:35 2022, Carsten, , 2nd DAQ
|
Switched the CAEN TDC back on and changed the threshoolds for the ADC to:
unsigned short caen_V785AH_threshold_mod0 [32] =

|
Sun Apr 3 11:40:48 2022, Shahab, Yuri, Detectors, 245 MHz Resonator tuned to new frequency
|
resonance frequency changed from 243.2 MHz to 244.692 MHz by reducing the value of both of the plungers from 395 to 325. Now after movement, the peak is
on the resonance. |

Thu Apr 7 08:14:03 2022, Yuri & Danyal, General, 229Th89+ line in Schottky
|
GLOBAL calculations for the "content" of the Th line in the Schottky spectrum
(380 MeV/u exit energy, equilibrium charge state distribution)
|
|
Tue Apr 5 23:07:34 2022, Carsten, Accelerator, 229Th89+ identification after re-tuning of the ESR
|
The ESR was retuned this aftenoon since the it was unclear if we still sit the 229Th89+ line.
This lead to new ring settings (data with all the settings will be put in tomorrow).

Sat Apr 9 16:55:19 2022, Rodolfo, Laser,
|
16:15 I have changed the dye (of both oscillator and amplifier).
16:27 I have increased the pump energy (@ 532 nm) from 476 mJ to 507 mJ.
