Riassunto

Nel presente lavoro si riferiscono i risultati di alcune misure condotte in alta frequenza, per studiare l’influenza di un campo magnetico trasversale sulla tensione di innesco della scarica in un gas. Tali misure sono state eseguite per l’aria, alle pressioni di 0,1; 0,5; 1,0 mm Hg e con frequenze di 10; 15; 20; 25; 30 MHz. Il campo magnetico è stato fatto variare da 0 a 650 gauss ed il tubo da scarica usato era ad elettrodi cilindrici. I risultati mostrano una forte influenza del campo magnetico sulla tensione d’innesco della scarica; essi vengono discussi e confrontati con quelli ottenuti daS. C. Brownet al. e daJ. S. Townsendet al. che sono i soli che si trovano nella letteratura.

Summary

In this paper are reported the results of some high frequency measurements, carried out in order to study the influence of a transversal magnetic field on the breakdown voltage of a gas discharge. These measurements were performed in air at 0,1, 0,5; 1,0 mmHg pressure and at 10; 15; 20; 25; 30 MHz. The magnetic field was made to vary from 0 to 650 gauss and the emploied discharge tube had cylindrical electrodes. The results show a strong influence of the magnetic field on the breakdown voltage of the discharge. Our results are discussed and compared with those ofS. C. Brownet al. and ofJ. S. Townsendet al. which are the only ones published.
