Effect of avalanche-type barrier discharge on a silver halide photographic material in the case of blocked ionic conductivity
- Kuban State University (Russian Federation)
Imaging of avalanche-type barrier gas discharge excited by single videopulses {approx}7 {mu}s long is studied via chemical activation of an ion subsystem of microcrystals of silver halide photographic emulsions by 1-phenyl-5-mercaptotetrazole. Using 'Retina' commercial X-ray film and specially fabricated photoemulsion microcrystals with effective surface and deep electron traps as an example, the selective gas-discharge sensitivity of photographic layers to applied-voltage polarity is detected. It is shown that their sensitivity to barrier discharge ignited by negative-polarity pulses (on the electrode with a photographic material) is higher than in the case of positive pulses, irrespective of the photographic material's position in the capacitor system.
