O, really!? Thank you very much for this video! It is actually not so complicated as I thought.

Hi Adrian: yes, I specifically had you in mind while I was recording this! I was going to ping you and let you know, but you already found it. You are indeed correct that performing the full gun alignment is not too daunting of a task (though to be sure, it is far more involved with this configuration compared to an S-FEG with no monochromator). You're welcome and thanks as always for your support.

Hello! That really doesn't look like a big trouble and it doesn't take that much time! Do we need to wait for stabilization after these? And the same thing for the Mono excitition that you didn't do here. I remember in EELS video after mono excitation you said to leave the microscope alone for a night 😀

Yes indeed, doing the gun alignment (even with the monochromator) isn't too difficult (and the provided instructions are very good, too). As far as time to stabilize the mono after excitation, leaving it overnight is indeed probably overkill (though not a bad idea if you have the time to allow it); I think the apps person from ThermoFisher said that a couple hours was sufficient for this.
