A technology was developed and ion-beam modification of copper samples manufactured at the Institute of Applied Physics of NAS of Ukraine and CERN was carried out. It is shown that the coating of copper with a thin layer of titanium nitride and additional irradiation with 300-keV Ar ions raises the vacuum breakdown voltage by 50%, and reduces the field emission current. The Fowler-Nordheim equation is obtained for finding the value of the field emission current for the relativistic case. It has been shown experimentally that an external magnetic field, with a strength of 0.4-0.5 T perpendicular to the electric field, does not lead to a decrease in the probability of high vacuum breakdowns.
