Measuring screen current on FEI Tecnai S/TEMs

Hey EM aficionados! I've spent a lot of time with our FEI Tecnai F20 as of late, getting it ready to be re-released back into the wild after being "injured" for over a year (ha ha). During this time, I came across a rather useful bit of information (as per our FSE) that you may find useful in regards to quantifying the beam current (which doesn't appear to be a standard option in the bottom information panels on most Tecnai instruments). Stay tuned for just under 4 min to see just how to do this (you may need to be logged in to a supervisor Windows account to be able to access the necessary program). Thank you for your support, my fellow EM aficionados, as we close in on 6,000 subscribers! 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 three S/TEMs, three dual FIB/SEM systems (a new one recently signed off on), and half of an SEM and this keeps me very busy!
