The KNI's Helium & Neon Focused Ion Beam Microscopy lecture, presented by Matthew Sullivan Hunt, PhD. Lectures on SEM (https://youtu.be/Zh21tp3aPEw) and Ga-FIB (https://youtu.be/3eSzisbNcGo) are also available.
Note that I never *explicitly* stated that once we have a trimer, we mechanically tilt the top of the column so that the beamlet from *one* of those three trimer atoms is directed down the optical axis. Using a single atom source is very important for getting great He- and Ne-FIB resolution. See the full explanation of beam tilt here: https://youtu.be/RvxFWvbQ3JY?t=37
Download the lecture slides (with complete slide notes) from the KNI's Box Directory, https://bit.ly/2O5sN6e. Different versions of each microscopy lecture exist there, including this lecture version with videos embedded, and .pptx & .pdf versions without the videos but with several more slides (this lecture version has been purposely condensed to fit into one hour).
