FIELD: acceleration technology. SUBSTANCE: transducer has two electrodes mounted in accelerator vacuum chamber above and below median surface, power source, loading resistors, and summing amplifier; electrodes are arranged symmetrically to median surface of accelerator and connected through loading resistors R to positive terminal of power source and through coupling capacitors, to summing amplifier inputs; negative terminal of power source is connected to grounded conducting coating of vacuum chamber. EFFECT: improved accuracy and stability of charged-particle beam current measurement. 1 dwg
