Hi Andrew!
I know how to calculate the Ion Cyclotron-Frequency.
But how did you choose the diameter and the number of windings of the RF-coil?
Or did you just take the available space according to the magnetic field and distance to magnet to achieve the right B-field?
I talked to several people. Some told me to calculate a kind of resonance frequency (coil + wires as capacity) others told me to just take a "few" windings.
I have about 1 kW @ 13,56 MHz available using a MFJ-962-D tuner as matching network ...
BR,
Werner

Re: ECRF injector sucessful RF ionization
The diameter was chosen based on space available(the spacing between the feedthroughs). The number of turns was simulated in NEC, and chosen to produce the highest transverse(perpendicular to B) electric field.
