FIELD: physics. ^ SUBSTANCE: proposed method comprises arranging long-persistence phosphor-target on flow path, irradiating said target by electron flow, producing on target surface of luminescent image of electron flow section and determining electron flow distribution over said section. Note here that said long-persistence phosphor-target represents nano-structure Be2(Si0,8Ge0,2)O4-based ceramics, while said distribution is determined quantitatively from said luminescent image of electron flow section converted from analog form into digital form. ^ EFFECT: expanded performances, development and control of accelerating hardware and high-precision electronics. ^ 5 cl, 4 dwg |
