from now on, everal beam setting will be different. We could not get the beam back to were it was before. When the scraper was pulled back by 2 cm, the loe/energy beam was visible again via cap. 
Schottky. However, no x-rays could be observerved during the target-on phase. 

Hence the interpretation:

beam position has change at least a few mm, at most 2 cm. 

Will now try to get a new overlap with target and need to adjust the detector position too.

All online - Si spectra are cleared.
