First observation of liquid xenon electroluminescence with a Microstrip Plate

We report on the first observation of electroluminescence amplification with a Microstrip Plate immersed in liquid xenon. The electroluminescence of the liquid, induced by alpha-particles, was observed in an intense non-uniform electric field in the vicinity of 8-\mum narrow anode strips interlaced with wider cathode ones, deposited on the same...
