Gas jet density about 1.1e12.      7   Thu Mar 25 11:42:14 2021 Martino Trassinelli DAQ TDC recalibration Check of the TDC spectrum:it is strange. Uwe and Jan recheck all the chain. Still strange behavior.        8   Thu Mar 25 13:29:22 2021 Martino Trassinelli DAQ mbs acquisition restarted TDC changed and acquisition restarted. We have now a 2D histogram time vs energy. We should have some clues to solve the mystery.      9   Thu Mar 25 19:20:24 2021 Martino Trassinelli General Switch to Be-like line Tuning the beam for the Be-like U from capture in Li-like U.  Energy setting up to 39.293 MeV/u.      10   Thu Mar 25 23:59:46 2021 Robert Runs Data run for Be-like We started a run with cooler energy set to 21715 V, corresponding to 21515 V with space charge correction for Be-like from capture.      11   Fri Mar 26 07:26:48 2021 Robert Runs typical cycle for the be-like measurement        12   Fri Mar 26 08:35:25 2021 Martino Trassinelli Runs End of the Be-like beam Problems from the high frequency in unilac. We stoped the acquisition at 6:50 corresponding to the lmd file n. 1184.      13   Fri Mar 26 09:10:02 2021 Martino Trassinelli Analysis Low energy Li-like beam TDC vs ADC from Ge detector Arrival time vs energy of the Xray from the Ge detector during the beam with Li-like U at 39 MeV/u. Prompt data are visible, due      14   Fri Mar 26 20:42:31 2021 Robert Analysis image of the photons from the be-run around 16 photons in the right energy range after ~5 h of integration.      15   Tue Mar 30 11:03:17 2021 Robert Runs data run for Li like We startet run on Tuesday 2 am with ~4E7 decellerated ions.  We get a count rate of ~40 cts per hour in      16   Tue Mar 30 11:24:51 2021 Martino Runs Typical good cycles for He-like beam        17   Thu Apr 1 21:24:14 2021 Martino Runs H-like ion beam started for He-like Starting the acquisition for the He-like U with a H-like U beam at 41.035 MEV/u Gas jet detector: 2.38E12 part/cm2      18   Sat Apr 3 12:01:01 2021 Robert Analysis Line energies for Germanium detector        19   Sat Apr 3 12:03:57 2021 Pierre-Michel Analysis X-ray spectrum Live X-ray spectrum from U91+ at 41 MeV/u, accumulated within 35.6 h according to Go4.      20   Sun Apr 4 15:26:57 2021 Robert Runs stability of ion beam current during He-like run graph starts covers the whole he-like run from Thursday evening to monday afternoon      21   Mon Apr 5 16:07:36 2021 Robert Runs He-like run run started thursday 21/04/01 20:00, ended monday 21/04/05 15:20,  time span of 91.5 h,      22   Tue Apr 6 14:27:59 2021 Martino Runs electron cooler voltages Parameter  U90+ @ 30.160 MeV/u  U91+ @ 41.035 MeV/u     U89+ @ 39.293 MeV/u  gamme          1.0324                  1.04407      23   Tue Apr 6 14:47:26 2021 Robert Analysis stability of the spectrometers during He and Be run the large spike in the outer spectrometer is attributed to an open door of experimentierhalle, which we closed at ~17:00 at 21/04/05.      24   Tue Apr 6 14:59:19 2021 Robert Runs second Be-like run run started 210405 17:50 run ended 210407 11:30 no of files: 1452      25   Wed Apr 7 11:51:54 2021 Robert Runs stability of ion beam current during Be-like run        26   Wed Apr 7 11:52:52 2021 Robert Analysis spectrum He-like        27   Wed Apr 7 11:53:33 2021 Robert Analysis spectrum Li-like        28   Wed Apr 7 11:59:01 2021 Robert Analysis spectrum Be-like
