Yes, very interesting example (and device),
Respect to DC current EM radiation, In that time Richard bring an
interesting example of 20 kV electron rectilinear beam rendering a
frequency of 34.6 EHz, the calculus it was quite right, but that
frequency it is not EM waves radiated by electrons but a "matter wave'
frequency... (idem with car analogy = not charged and acelerated
cars :) do not radiates EM waves, but may have a matter wave
asociated to them).
Each waves are the matter waves. The speed is the particles mass dependent.
