Electrostatic deflection (scope-type) CRT set-up

After my video on the electron mass, I thought its worth looking at setting up and electrostatic deflection tube basics to produce a dot on the screen. Although the acceleration voltages in these tubes are lower the electron gun assemblies can be a little more complicated than in an old TV CRT.
