Abstract
Comparative performance and stability properties of a cathodic vacuum arc plasma source based on dc arc discharge with a magnetic confinement of a cathode spot and plasma stream focusing are presented in case with grid insert placed within the hollow anode and without it. The arc stability becomes worse while the magnetic field increases, and at magnetic field strength above 7-8 mT in case without insert the discharge extinguishes. Use of the anode insert makes it possible to provide stable arc operation in the magnetic field up to 20 mT and increase the output ion current to 8.5 A at an arc current of 100 A.
