A device for coupling ionization energy into an ion or electron source, which is excited inductively or inductively-capacitively is provided. The device includes: a discharge vessel for a gas, which is to be ionized; a coupling coil, which is wound around the discharge vessel and feeds in a high frequency energy, which is required for plasma excitation; a coupling capacitor, which is electrically coupled to the coupling coil; a high frequency generator, which is electrically coupled to the coupling coil. The high frequency generator forms, together with the at least one coupling capacitor, a resonant circuit. The high frequency generator includes a PLL controller for automatic impedance matching of the resonant circuit, so that the resonant circuit can be driven at a resonant frequency.
