X-ray delivery stable in intensity, 1300-1400 mJ at 8150 eV SASE.

user experiment 3430 (Zastrau / Mishchenko)

Horizontal jitter compensated with intermediate focus (by overfocusing with CRL in XTD1, and focus on target with CRLs in HED OPT.
Beam drifts compensated by M2, M3 mirror feedback

RELAX laser shots on 10 um Cu foils, last 12 h pumping a Cu 22+ resonance K line. probing laser plasma at 0, 5, 10, 20 and 50 um spatial offset

Completed our data set. We now have 100fs resolved 2d transmission images and K-resonance from +1 ps to -100 ps delay time.

Successful user experiment.
