Determination of fast electrons energy absorbed in the air by measuring the concentration of ozone synthesized in electron beam plasma

Method of determination of the electron beam energy absorbed in the air by measuring the concentration of ozone synthesized in electron beam plasma is proposed. It is shown that the energy of electrons absorbed in the air increases with an increase in the air gap and the atomic number of the target, and reaches the maximum value 0,036 J for a lead target at a distance 17 cm from the output foil. The highest value of the relative proportion of reflected electrons in the total electron beam energy absorbed in the air (0.45) corresponds to a lead target with a gap value 9 cm. The value of this relative proportion is determined by combination of the atomic number of surface material, the number of electron reflections and the length of the air gap. Obtained calculated average value of the ideal specific energy yield of ozone with taking into account the reflected electrons energy absorbed in the air (413 g (kW h)-- 1 ) can be used to determine the value of absorbed in the air energy of the electron beam generated by the RADAN-220 accelerator, when using reaction chambers of any size and configuration, with targets and walls made of any materials.
