How to SAFELY take PERFECT zone axis selected area diffraction patterns every time

Hey fellow EM aficionados! I rerecorded this video (and took down the previous one) because I want to make sure I'm giving you the most accurate information to safely and effectively use your S/TEM instrumentation. The main (and very significant) difference in this version is how to properly measure the intensity in your patterns to ensure you are not potentially causing damage to the Ceta CMOS camera. A big thanks to my man Garrett for pointing out my oversight in the previous version. Now, on to the video! Selected area diffraction work is a necessary (essential if you saw my last MSA webinar) technique for today's S/TEM operators working in the physical sciences. The best (or at least most aesthetically pleasing and easily indexed) SADPs will be those where the incident beam is well-aligned with a crystallographic zone axis (ZA). Like many of you, I used to work myself silly meticulously tilting the stage to try and obtain perfect ZA alignment, only to fall disappointingly short. Well, I'm here to demonstrate a clever technique (using our Themis Z S/TEM) where you only need to get the ZA alignment in the ballpark via stage tilting before employing a neat little trick with the dark-field beam tilt controls. Ultimately, this will save you time as well as your precious sanity! Finally (and most importantly), I cover safe and optimal use of the Ceta CMOS camera to record your ZA SADPs. Thank you for your support, my fellow EM aficionados! Please like, subscribe, and share and leave any questions or comments you may have and I will do my best to reply as soon as possible. Video topic requests are always welcome and appreciated; I enjoy making these videos and wish I could make them more frequently, but the demands of my job make it tough to do so; I’m in charge of 3 S/TEMs, 2 dual FIB/SEM systems, and 1 SEM and this keeps me very busy!
