Some remarks to construction of ECR ion source hexapoles

This paper gives performance data for construction of suitable hexapoles for Electron Cyclotron Resonance Ion Sources (ECRIS). Permanent magnets are made from Nd-Fe-B magnetic material. The main attention is given to hexapoles with inner diameters of /spl phi/ 3.6 cm at different hexapole thicknesses of 1.3-6 cm. Some remarks on construction of hexapoles are presented.
