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 ...
