5FP7 project starting with the focusing coil.

[Mike Watterson]

If you want to have any scan rate, like a scope has, then the EHT circuit needs to be separate from the scanning. For up to maybe 2 kV or 3kV a diode multiplier is needed, otherwise use he LOPT in a standalone boost or Cuk inverter using a 16 kHz approx frequency. Maybe 20 kHz to 40 kHz will work.

A pair of high power IC audio amps can drive the scan coils.
