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. |

A publication on scraping systems suggested by Siegbert.
In the study they have used cylindrical "high-quality" slits. "High-quality" stands for well polished surface
with surface roughness <50nm. The material of the slit is Tungsten Carbide. |
