Movie of the electron beam - 23rd of December 2009

1 - The Sample Chamber has an extra port through which we can see the sample in the Sample Chamber from the front side. This makes is possible to place a CCD Camera behind this window and monitor the beam position and shape by using a phorphor screen at the sample position.

2 - The CCD image. In the center you can see the phosphor screen positioned in the center of the Sample Chamber.





Here you can see the movie with the electron beam visible on the phospor screen.
