Shift summary for 10.8.2023

X-ray delivery

• 9.3 keV, up to 181 pulses at 564 kHz, 1.8 - 1.9 mJ

Optical laser delivery

• PP Laser, 800nm, 50 fs, up to 181 pulses @ 564 kHz and 91 pulses at 282 kHz, stable delivery

Achievements/Observations

• Increased MBK_PSLIT aperture to fully fill the mirror's aperture
• Issue with coordinated MKBs motion solved with the help of EEE and CTRL.
• PP laser was aligned to IRU
• Established temporal overlap between PP laser and X-rays
• Continuation of automatic jet alignment testing
• Measured pump-probe data at different delays and fluences

Issues

• Injector Y stage is moving down without giving sany move command, DOC was informed. PLC experts will contact morning shift crew to investigate further
• Astigmatism of PP laser beam prevents optimal focusing of the beam at the interaction point. LAS has been informed
