The first main results of creation of the numerical electromagnetic code "SOM" for research of a virtual cathode at the presence of plasma are presented. The obtained results are the part of the project № 1569 «Development of the collective ion accelerator, based on plasma vircator and periodic magnetic field », performed by agreement with Science and Technology Center of Ukraine. The description of algorithm of a numerical simulation of the virtual cathode in the cylindrical drift chamber is adduced. The implementation of algorithm is carried out by the way of complex of the programs in C++ language. The numerical calculations are made for the upgraded experimental installation "«Agate". It is shown, that at joint injection of a high-current relativistic electron beam (Ub = 280 keV, Ib = 4,6 kA) and low-energy, low-current an ion flux in the drift chamber the ion virtual cathode arises, which is pulses periodically. The pulsation frequency makes for 300 MHz hydrogen and 100 MHz for ions of nitrogen. It leads to low frequency time modulation of an output current.
