Laszlo | General | quick comparison between different scraping positions | 2021 |
So far we did 3 scraping positions:
- 30mm away from beam axis (lmd72-75)
- 25mm away from beam axis (lmd78-80)
- 20mm away from beam axis (lmd76-77)
below one can see the comparison of the scrapings for the DSSSD spectrum. Please mind the different amount of data collected |
