It is an interesting problem'to study the lower pres-sure limits of streamer flash-over when a positive impulse voltage is applied to the needle-of-needle-plane electrode (gap length 11cm). On the X-ray film -which was put on the coplaner with electrode axis, the trace of first streamers disappears in, the region of 15_??_10 mmHg, but the light pulse of photomultiplier indicates that streamer flash-over also occures at 4 anmHg.
