Abstract
Important features of the instrument described are the simplicity of its design, the fact that no transmission cable is used between excitation coil and oscillator, and the ability to compensate for changes in the load, represented by the plasma in the discharge lamp. The generator operates at 149 MHz, which is much higher than the normal frequencies prescribed for the industrial, scientific and medical bands, but still allows coils to be used instead of cavities. The maximum power level of the generator is 192 W, while the typical power output to the discharge lamps is of the order of 60W.Keywords
