These are the runs after the septum was repaired on 16.05.

ca. 18:00 ? ~3.0e7 223222 504-505 8121 601.62 - 601.405 0.005 5s 4 DAQ2 late start
18:11 ? ~3.3e7 223222 506 8122 601.62 - 601.405 0.005 5s 4 aborted, ions are rapidly lost after Bahnverlagerung
18:33 4.5e7 ~3.7e7 223222 507-509 8123 601.62 - 601.405 0.005 5s 4 removed all scrapers, beam life time is better, high intensity, slight instability in bunching, ion intensity at the end: 1.4e7, DC Trafo was in saturation so ampl. was turned down
19:32 ? 3.7e7 223222 512 8125 601.62 - 601.405 0.005 5s 4 rf bunching amplitude decreased from 350V -> 280V
20:00 ? 3.6e7 223223 514 8127 601.745 - 601.32 0.01 5s 4 43 steps of laser, therefore 1 step offset from loop to loop, laser already of ?
20:30 ? 2.9e7 223223 520-522 8129 601.760 - 601.320 0.01 5s 6 aborted after 3 loops, laserstabi was off, probably during hole measurement
21:01 ? 3.6e7 223223 524-528 8130 601.760 - 601.320 0.01 5s 6
21:30 ? 3.4e7 223223 529-532 8131 601.760 - 601.320 0.01 5s 6 coasting beam now !!!
22:10 ? 3.7e7 223223 534-537 8132 601.760 - 601.320 0.01 5s 6 Night shift took over.
22:40 4.4e7 3.6e7 223223 539-542 8133 601.760 - 601.320 0.01 5s 6
23:52 3.8e7 3.2e7 223223 545-548 8134 - 8135 601.760 - 601.320 0.01 5s 6 Switched off the nitrogen before this run, stopped acq. after 4 loops (laser gone), PMT north saw a lot of noise? (ID:78) -> larger files.
00:39 4.3e7 3.2e7 223222 552-555 8136 601.760 - 601.320 0.01 5s 6 The secondary DAC always requires 2-3 restarts until it is working.
01:10 3.8e7 3.0e7 223222 557-558 8137 601.760 - 601.320 0.01 5s 6 Laser moved away during the third loop, acq. stopped.
01:33 4.2e7 3.1e7 223222 561-564 8139 601.760 - 601.320 0.01 5s 6 The previous laser scan was still running, restarted the acq. once.
02:00 > 4.0e7 3.4e7 223222 566-569 8140 601.760 - 601.320 0.01 5s 6
02:30 > 4.0e7 3.2e7 223222 573-576 8141 601.760 - 601.320 0.01 5s 6
02:58 4.2e7 3.4e7 223222 579-582 8142 601.760 - 601.320 0.01 5s 6
03:45 4.2e7 3.3e7 223222 585-589 8143 601.760 - 601.320 0.01 5s 6 Back to bunched beam mode
04:15 4.7e7 3.4e7 223222 594-598 8144 601.760 - 601.320 0.01 5s 6
04:43 4.4e7 3.4e7 223222 600-604 8145 601.960 - 601.520 0.01 5s 6 We changed the scan range Big grin
05:10 4.3e7 3.3e7 223221 606-610 8146 601.960 - 601.520 0.01 5s 6 It looks like the "overWavel" plots actually work better now, because the laser steps somehow are counted wrongly, leading to shifts between loops.
05:37 4.2e7 3.7e7 223221 611-615 8147 601.960 - 601.520 0.01 5s 6
06:27 ? ? 223219 616-618 8148 601.960 - 601.520 0.01 5s 6 Since Go4 was still running during startup we were not able to look into the data during the scan. After reduction of particle number, the dc trafo is no longer capable to measure to number of ions.
06:56 ? ? 223219 619-620 8149 601.960 - 601.520 0.01 5s 6
07:25 ? ? 223219 621-622 8150 601.9 - 601.7 0.01 5s 6 Changed the scan range t0 601.9-601.7 and reduced step increment to 0,005nm
07:56 ? ? 223219 623-624 8151 601.9 - 601.7 0.01 5s 6
08:20 ? ? 223219 625-625 8152 601.9 - 601.7 0.01 5s 6 Restarted scan without new injection, DAQ2 was not running during this scan
08:44 ? ? 223220 626-627 8153 601.9 - 601.7 0.01 5s 6 Reduced Loop number to 4 (aborted after 4 completed scans)
09:03 ? ? 223220 628 8154 601.9 - 601.7 0.01 5s 6 Reduced Loop number to 3 (before starting a new scan)
09:17 ? ? 223221 629 8155 601.9 - 601.7 0.01 5s 6
