These are the first runs of the substitute beamtime. Time ESR-intensity ESR-intensity after orbit change cooler-HV LMD-DAQ2 file nr LMD-DAQ1 file nr scan range(nm) step width increment (nm) dwell time(s) n loops comments 02:00 ? 8.0e6 223217 632 8158 601.95 - 601.734 0.005 5s 5 Resonance found in first scan. The resonance is much broader due to a broader ion beam. 02:28 ? 7.0e6 223217 633 8159 601.9 - 601.7 0.005 5s 5 Same injection. 02:52 ? 6.3e6 223217 634 8160 601.9 - 601.7 0.005 5s 5 Same injection. Adjusted gates in go4. 03:14 ? 5.6e6 223439 637 8163 601.9 - 601.7 0.005 5s 5 Same injection. Auto-impedance enabled -> correct voltages. NTCAP started shortly after scan start. 03:35 ? 3.0e5 ? (under range) 223439 639 8164 601.9 - 601.7 0.005 5s 5 Scraped the lower charge state beam by moving S1HA to pos. -30 (from the left). 04:50 ? 1.1e7 223439 640 8165 601.9 - 601.7 0.005 5s 5 Laser beam position slightly corrected for new ion beam position, see ID:84. 05:05 ? 1.0e7 223439 641 8166 601.9 - 601.7 0.005 5s 5 See picture (this + previous run) 05:21 ? 1.0e7 223439 642 8167 601.9 - 601.7 0.005 5s 5 Moved S1HA to -35 to get rid of the charge transferred beam. 05:33 ? 9.0e6 223439 644 8169 601.9 - 601.7 0.005 5s 5 05:52 ? 9.0e5 223439 645 8170 601.9 - 601.7 0.005 5s 5 Scraped main beam for lower beam intensities. There were some issue with the acquisition, and thus there are some empty files 06:08 ? 4.e5 223438 650- 8172 601.9 - 601.7 0.005 3s 25 07:11 ? 1.15e7 223438 653 8173 601.9 - 601.7 0.005 3s 25 laser scan was not started 07:17 ? 1.03e7 223438 654-656 8174 601.9 - 601.7 0.005 3s 25 08:33 ? 6e6 223438 658-660 8176 601.9 - 601.7 0.005 3s 25 ESR scraper not in 09:27 ? 5.5e6 223438 661-667 8178 601.9 - 601.7 0.005 3s 25 XUV detector running again, signal of PMT north and middle in att. 2 10:15 ? <<1e6 223438 668 8179 601.9 - 601.7 0.005 3s 25 very low beam intensity Note: PMT north does not see a resonance. Note: PMT north does see a resonance after changing to the broadband PMT.
