TimeSIS-intensity cooler-HV LMD-DAQ1 (R4L-68) LMD-DAQ2 (R4L-41) scan range (nm) step width(nm)dwell time(s) comments
17:28 1.1e9 - 0083 7822 322.3-321.3 0.01 4 Wrong scan range
17:48 1.4e9 209618 0084 7823 322.3-321.3 0.01 4 Wrong scan range
18:10 1.6e9 - 0085 7824 323.2-321.2 0.01 4 acquisition on r4l-68 crashed
18:13 2e9 - 0086 - 323.2-321.2 0.01 4 acquisition on r4l-41 crashed
18:29 1.9e9 209618 0087 7826 323.2-321.2 0.01 4 An artifact is observed at about 644nm <-> 322nm fundamental wavelength
20:17 2e9 209609 0089 7827 323.2-321.2 0.01 4 Cu-mirror and XUV detector are not driven at the moment. It is unclear for how long this was the case. Optimization of the accelerator settings were done before.
21:12 1.6e9 - 0089 7828 323.2-321.2 0.01 4 Laser got wrong pulse widths during this scan and also during the last one.



At about 20:00 the slits were adjusted to the h=1 settings:

NI: 5mm
NA: -3mm
SA: -10mm (also the voltage for the Scitnilator in this pocket was increased to 1500V)
SA_Scraper: +14mm
