ID Date Author Category Subject Text   85   Tue May 31 07:29:11 2022 Ken Detectors XUV-Detektor Rate was very low: ~ 100Hz Adjusted Walk level and Threshold, new rate: 5kHz      66   Sat May 15 09:57:24 2021 Dayshift Runs Currently on schedule Enhance fluorescence rate and perform  laser bunch timing       Draft   Wed May 12 02:16:25 2021 Danyal, Lars Accelerator Ion beam position Laser Position with scrapers verified.  1HA: impossible to scratch laser beam, still there at -1.0 mm      1   Mon May 10 07:58:13 2021 Danyal General Telephone numbers and Zoom link Telephone numbers: ESR laser lab: +49 (0)6159 71 - 2882      2   Tue May 11 15:49:30 2021 Danyal General setting up ESR The operators are still busy extracting the beam from the SIS18 towards the ESR and injecting it into the ESR.       5   Tue May 11 18:29:35 2021 Danyal General first ions in the ESR        6   Tue May 11 20:14:43 2021 Danyal General bad ESR vacuum I just heard that the ESR vacuum is quite bad.  There was a small vacuum problem a while      8   Wed May 12 02:34:29 2021 Danyal General instabilities in ion frequency The ion beam moves around, pretty arbitrary. See picture.  ESR crew believes that it is not due to fluctuations      20   Wed May 12 13:11:58 2021 Danyal Accelerator short break between 13:30 and 15:30 There will be a short break (2 hours) this afternoon. Between 13:30 and 15:30.  The so-calles "super lense" in the UNILAC      21   Wed May 12 15:36:04 2021 Danyal Accelerator general power failure in ESR! (everything is off) The power in the ESR is off.  (also on the gas-target area on top of ESR) Electrical engineers are trying to find and      25   Wed May 12 22:35:33 2021 Danyal General frev and fb Schottky frequency (189th harmonic) = 244.033662 MHz      30   Thu May 13 00:58:53 2021 Danyal DAQ unbunched ion beam        31   Thu May 13 01:01:27 2021 Danyal DAQ bunched ion beam        32   Thu May 13 01:05:45 2021 Danyal DAQ more stability by bunching Because the C3+ part of the ion beam is properly bunched, it is no longer so sensitive to the drifts caused by the e-cooler.       84   Mon May 17 21:43:56 2021 Danyal General The test beamtime was a success. Dear all, The test beamtime is now over.       17   Wed May 12 09:59:08 2021 Benedikt General Rigol DSG821 signal generator settings        40   Thu May 13 20:18:10 2021 Benedikt General New f_rev The ions were changed to a different speed today at 2 PM. The new revolution frequency is now 1.291278 MHz.      41   Thu May 13 21:00:48 2021 Benedikt General New reprate of the UV laser The lasersystem now operates at a reparte of 9.038946 MHz. This is 7 times f_rev (see previous post).      56   Fri May 14 11:01:33 2021 Benedikt Calibration Laser Beam adjusted The laser beam was adjusted in his position to overlap better with the ions.      57   Fri May 14 16:37:01 2021 Benedikt General Status update Right now, we have to adjust the ion beam a bit to overlap better with the laser beam. We keep the laser wavelength at resonance
