Study of the Avalanche to Streamer Transition in Glass RPC Excited by UV Light.
Protvino, 2002.- p.8, figs. 11, refs.:2.


Small glass RPC filled with Ar/Isob./Freon mixture has been exposed to light from UV laser. Dependence of avalanche-to-streamer transition process on the laser beam intensity and on high voltage applied to RPC were studied. Two types of streamer signal has been observed. Using CCD TV camera, pictures on multi-streamer propagation over RPC were obtained.
