# Induction Heating for Outgassing the Beamline

Hi,
I want to heat the FEL beamline for the outgassing process with an induction heater. What frequency should I use in the driver circuit of the heater?
The geometry of the beam line as you can imagine is cylindrical.
And do you have any experience about it? If its so, I will be appreciated if you could give me some advice about this point.

Can you test it? :D
Resonance should appear at the order of $T\approx \frac{radius}{c}$ and multiples of that value. But that needs a frequency in the MHz-range, I don't know if your induction heater works with that.
Don't rely on that, I did not heat any beamlines before.
