problems with machine operation

very low yield at 1.8keV, took ~2hrs tuning time to get 600uJ (linear taper)

SA3 cells opened without us knowing when hv was changed

observed strong pointing change (and beam profile shape) when changing

- SASE3 pulse timing

- photon energy

pointing change with changing photon energy was such that the beam would make it through the GATT only partially (att. 1). this is unprecedented.
