Hung,

Can you please explain what an "ionic field" is?

I know perfectly well what an ion is and I know what an electric or magnetic field are, but I can not understand what you mean by an ionic field.

Is it:

A stream of ionized particles (gold in this case) as in a plasma stream?

The electric (electrostatic) field generated by an ion due to its charge imbalance?

Something else?
