Characteristics of a fluorescent lamp operated on high frequencies have already been reported in many papers, but the phenomena of the discharge on high frequencies has not already been analizedyet.
In this paper the physical concepts of positive colum of fluorescent, lamp on high frequencies are treated. It has been learned that the light output on a constant current in frequency region between 60c/s.and 2kc/s decreases as the frequency increases It is considered that this results from the full of the electron temperaure due to a decrease in the effective ambipolar diffusion coefficient in such a frequency region.
On the other hand, light output increases in the frequency region above 2kc/s. It seems that electron temperature rises to compensate the decrease of efective ionization cross section in this frequency region Moreover the effects of tube diameter, bulb temperature, gas pressure and current wave form upon out-put of resonance radiation on high frequencies hava has also been investignted theoretically andexperimentally.
