Electron beam Pumped Ultraviolet Light Source (240-267nm) based on GaN/AlN MQW Structures with Output Pulsed Power of Several Tens Watts

Using electrons with energy about 15 keV, electron source based on a ferroelectric cathode and GaN/AIN MQW Structures the following values of power of UV-pulse radiation were obtained: $50 \mathrm{~W}(\lambda=240 \mathrm{~nm}, J=2240 \mathrm{~mA}), 69 \mathrm{~W}$ $(\lambda=248 \mathrm{~nm}, J=2500 \mathrm{~mA}), 71 W(\lambda=267 \mathrm{~nm}, J=2340 \mathrm{~mA})$
