| Zusammenfassung: | In optical experiments where double beam techniques are not applicable, a stable light source is desirable. This paper describes a current regulator for a dc cold cathode hydrogen gas discharge used as an ultraviolet light source. In addition to the discharge current, the light output depends on factors such as gas pressure, but reasonable stability is obtained by simple precise current regulation of ±0.1%. |
