摘要
Abstract
A 2. 45 GHz electron cyclotron resonance ion source with permanent magnets has been developed. Its outline dimension is 160 mm in diameter and 90 mm in height, the discharge chamber's dimension is 70 mm in diameter and 50 mm in he-hight. The microwave window is made of a φ50 mm×10 mm BN disk and two φ30 mm×10 mm ceramic disks. This ion source adopts a three-electrode extraction system and works in the pulsed mode. When the microwave input power is 300 W, the air inflow is 0. 4 mL/min, a more than 30 mA peak current of the nitrogen beam can be extracted from a 5 mm emission aperture at 100 kV extraction voltage. The diameter of the beam uniform area on the working plane is more than 200 mm.关键词
