19 Feb 2023, 08:08 Hand over from night shift
Added polarizer in the PAM beam in the optics hutch, reequilibrated reference arm of PAM
19 Feb 2023, 08:09 Darks taken for JF 1 and 2
19 Feb 2023, 08:28 Check sample alignment, correct for shot samples
19 Feb 2023, 08:33 Beam was off on Zyla, M3 feedback had to be restarted this morning. May this changed the setpoint. New setpoint is now at 342.4
19 Feb 2023, 09:09 Aligned edge of Cu foil on Zyla, then moved ILM to get a sharp image of the edge, then focus RELAX beam to this position
19 Feb 2023, 09:11 OAPX motor is in permanent error state
19 Feb 2023, 09:17 Focal spot does not look nice,
19 Feb 2023, 09:40 Start shooting foils
19 Feb 2023, 09:51 Cu foil w Al B3-A3 , delay RELAX 100 fs before x-rays, run 257, seems we destroyed foils next to it
19 Feb 2023, 10:16 DOC called, OAPX is working again, reason unknown, seems to be an issue with the encoder. Needs checking the encoder on site.
19 Feb 2023, 11:09 Finished aligning samples, preparing for shot
19 Feb 2023, 11:15 Cu foil w Al B3-A1, delay RELAX 200 fs before x-rays, run 260
19 Feb 2023, 11:23 Cu foil B3-B2, delay RELAX 200 fs before x-rays, run 262, sample next to it was damaged
19 Feb 2023, 11:39 Cu foil B3-B3, delay RELAX 200 fs before x-rays, run 264
19 Feb 2023, 11:46 Aligning grids
19 Feb 2023, 12:07 OAPX again in error state, used this time AY rotation instead, did not really change the focal spot. Add this motors to the switcht off
19 Feb 2023, 12:14 Cu mesh 2000 C3B3, delay RELAX 200 fs before x-rays, run 266
19 Feb 2023, 12:21 Need much longer delays, will go to RF locking
19 Feb 2023, 12:43 Phase shifter device was stuck in moving state, restarted
19 Feb 2023, 12:45 Cu mesh1000 C3B1, delay RELAX 2000 ps before x-rays, run 268
19 Feb 2023, 13:00 Cu mesh 2000 C3B2, delay RELAX 500ps before x-rays, run 270
27019 Feb 2023, 13:07 Seems that RELAX does not hit exactly in the field of view, change to configuration CRL4B
19 Feb 2023, 13:19 Cu mesh HEX 1000 C3A1, delay RELAX 500ps before x-rays, run 272
19 Feb 2023, 13:22 Shot is fine, stay with CRL setting, realign samples
19 Feb 2023, 13:50 DOC called, some motor flags have been changed for OAP_X. hopefully ito works until tomorrow
19 Feb 2023, 13:54 Cu mesh2000 C2A5, delay RELAX 100ps before x-rays, run 274
19 Feb 2023, 14:00 Cu mesh2000 C2A3, delay RELAX 20 ps before x-rays, run 277
19 Feb 2023, 14:06 Cu mesh2000 C2A2, delay RELAX 20 ps before x-rays, run 280
19 Feb 2023, 14:13 Cu mesh2000 C2A1, delay RELAX 500 ps before x-rays, run 284
19 Feb 2023, 14:17 Cu mesh2000 C2B1, delay RELAX 1000 ps before x-rays, run 287
19 Feb 2023, 14:23 Cu mesh2000 C2B2, delay RELAX 1000 ps before x-rays, run 290 PPU was open before shot and closed during shot
19 Feb 2023, 14:27 Cu mesh2000 C2B3, delay RELAX 1000 ps before x-rays, run 291
19 Feb 2023, 14:31 Cu mesh2000 C2B4, delay RELAX 80 ps before x-rays, run 295
19 Feb 2023, 14:35 Cu mesh2000 C2B5, delay RELAX 666 ps before x-rays, run 298
19 Feb 2023, 14:38 Moved Siemens star in (pos 25), run 300, is out of range, tried then pos 2, visible in live view, run 301 |
