WEPAB191	Magnet System for a Proton/helium ECR Ion Source	3066
	M.S. Dmitriyev, K.G. Artamonov, M.V. Dyakonov, M.I. Zhigailova MEPhI, Moscow, Russia
	The study of the magnetic system of ECRIS with operating frequency of 2.45 GHz for producing protons and double-charged helium ions has been carried out. The results of the numerical simulation of the ECRIS magnetic system based on permanent magnets have been performed. The possibility of shifting the ring magnets in both injection and extraction regions is considered to adjust maximum and minimum values of the axial distribution of a magnetic field in a plasma chamber. The possibility of shifting the bar magnets of the hexapole is shown to provide the adjustment of the radial magnetic field Brad at the chamber wall. Additional solenoids are introduced to the system for providing the required Binj and Bext adjustment and tuning the axial magnetic field distribution including the minimum on the axis Bmin. Furthermore, the magnetic system allows to switch the operation mode of the ECR source to the microwave mode.

The study of the magnetic system of ECRIS with operating frequency of 2.45 GHz for producing protons and double-charged helium ions has been carried out. The results of the numerical simulation of the ECRIS magnetic system based on permanent magnets have been performed. The possibility of shifting the ring magnets in both injection and extraction regions is considered to adjust maximum and minimum values of the axial distribution of a magnetic field in a plasma chamber. The possibility of shifting the bar magnets of the hexapole is shown to provide the adjustment of the radial magnetic field Brad at the chamber wall. Additional solenoids are introduced to the system for providing the required Binj and Bext adjustment and tuning the axial magnetic field distribution including the minimum on the axis Bmin. Furthermore, the magnetic system allows to switch the operation mode of the ECR source to the microwave mode.
