Training session SEM - Pt08

This is the training session SEM Scanning Electron Microscopy. Part 1 contains a general introduction on SEM. The machine used is a Tescan Maia 2016 outfitted with a Oxford EDS 50 detector. This training is part of our program to put our training sessions online and in 14 clips we go through all the operational procedures including EDS sessions. In between the guided operations you will find lot of extra tips and information on the concepts and underlying technologies. This part 08 contains: -column-centering on sample -stigmatic correction on sample -insertion and use of the motorized backscatter detector -simultaneously use of multiple detectors Direct links to each clip and its topic: Pt01 https://youtu.be/i0sm_03YO4s -General introduction to the online concept of the SEM training -Startup and login -loading configuration file -error dialogs and control indicators Pt02 https://youtu.be/cA9TKvsTml4 -main icon bar -camera interface Pt03 https://youtu.be/FtJu7w2PORM -continuous scanning mode -the main control panel -the use of trackball and dedicated nobs -detector menu -beam on button -vacuum level indicators -purpose of main door loading Pt04 https://youtu.be/FI8qg6ax2Qw -chosing correct voltage and current Pt05 https://youtu.be/xi41CAxNiIM -loading sample through load-lock (red box protocol) Pt06 https://youtu.be/CLwJh8DH5Dg -raising stage to correct working distance WD (red box protocol) Pt07 https://youtu.be/Z9UWWtCO7Jw -calibration: Auto Gun-centering Manual Column-centering Stigmatic Correction Pt08 https://youtu.be/PmuDLIv6A2I -column-centering on sample -stigmatic correction on sample -insertion and use of the motorized backscatter detector -simultaneously use of multiple detectors Pt09 https://youtu.be/1GqsTmGbbcU -procedure for saving images the sample -saving image parameters -why and when to use averaging of multiple images -saved image resolution vs spot size Pt10 https://youtu.be/e4bhQDnmzsw -secondary and backscatter detectors type of information -difference between in-beam and chamber position of detectors -doing measurements in saved images Pt11 https://youtu.be/zNX4PZudDIk -basics of EDS, Energy Dispersive Spectroscopy -point scans -spectra interpretations Pt12 https://youtu.be/rtLMTIeRrgU -linescans in EDS -differences of qualitive and quantitative EDS methods -quantitative measurements in EDS -the model used in quantitative measurements and its flaws Pt13 https://youtu.be/vCTp7geZZc0 -the mapping tool in the EDS -the newbies pitfalls in EDS mappings -quantmap vs normal mapping mode Pt14 https://youtu.be/Uy0flMBVcfc -shutdown procedure of the SEM
