The starting potential of a A-Hg cold cathode discharge tube with quartz wall was measured under irradiation. The following phenomena were observed;
(A) In d. c. measurement
(1) When irradiated with a germicidal lamp a remarkable rise of the starting potential was observed, showing the more rise, the higher the wall temperature.
(2) The rising effect by local irradiation was stronger when irradiated near the anode than near the cathode.
(3) The starting potential remained high even after stopping irradiation, showing remarkable after effect.
(4) High pressure Hg-arc, fluorescent lamp, incandiscent lamp, Al-spark, Cu, Fe and C-arc, and scattered light from window had also the rising effect.
(B) A feeble intermittent discharge operated by a. c. source was stopped by irradiation with low intensity u. v. -ray.
