Leakage of current from MITL with ceramic coating cathode
At the Angara-5-1 installation the experiments were carried out to study the processes occurring during the passage of current in a vacuum transporting line in which the cathode was protected by a ceramic coating. The linear current density was about 1–2 MA/cm; the time of the current rise to the maximum was ~100 ns. It is shown that in the case of coating the MITL cathode with ceramics, not all the current entering the MITL reaches its end.
