Physical Effects During Micrometeoroid Particles' High-velocity Impacts on Metal-dielectric-metal Film Structures

During particle impact experiments on metal-dielectric-metal (MDM) structures the effect of fluorescence from a formed conductive channel in dielectric was discovered and studied. This effect takes place when induced electrostatic field intensity is higher then 2-106 V/cm and the interacting particles have a mass 1-5-10-14 gram and speed 2-10 km/s. It was noticed, that fluorescence intensity depends on capacitor voltage, with the conductivity channel resistance measured at 104-106 Ohm and the channel current at 10 - 4 -10 -3 A.
