Hi all,
I have been thinking some more about the possible forms a
probe might take. My initial idea was to effectively pipe the HV out
through the bottom of the coil. That approach might still be on but
the issue of loading is probably going to cause more than desirable
deviations in coil characteristics. So I have another which might
eliminate the need for a central shield.
Suppose the structure is graded such that it has a voltage
profile matching that of the coil. Will that do it? Probably only
only at Fr. If several probes having different gradings were made,
comparisons could be done. Equalization along the probe's length
might well be necessary but it would get us to the point of having to
deal only with low voltages/currents at the base where it exits the
coil form. And the shunt impedance could be made arbitrarily high.
There is the nasty impication that we would measure what we expect to
measure but different gradings might get around that problem if all
shunt impedances are equal.
Any thoughts from anyone?
