  to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation...
• HIGH POWER UV AND VUV PULSED EXCILAMPS
  radiation of Xe dimer band was recorded. at the pressures less than 12 atm. The duration 1/2 at FWHM and power P of. VUV radiation pulse as functions of Xe pressure are presented on Fig. 3. It is seen,. that the value of P increases at pressures up to 12 atm meanwhile radiation energy. decreasing...
