Paper Abstract

The main parameters of the electron beam multicharge ion source IMI-2 are given. Experimental results are also given. The IMI-2 electron-beam system (EBS) includes a short-focus electron gyn with a spherical cathode of diameter 16 mm and curvature radius of 9.5 mm. The perveance of the gun is 1,6 (mu) A/V3/2. The electron beam current can reach 2.5 A. An electrostatic and magnetic beam compression of ~103 allows one to obtain a density of the electron beam of not less than ~103 A/cm2 on a 30 cm length. A specific method of dosed injection of the atoms of solid-state elements to an ion trap by means of local pulse deflection of the electron beam was used in the facility 1. The electron-beam ion source (EBIS) IMI-2, Fig. 1, has a vertical design with an electron gun in the top section. The electron gun is mounted in a vacuum chamber of diameter 160 mm and length 500 mm. The vacuum chamber having a drift structure is inside the classical water-cooled solenoid with a completely closed magnetic circuit. An electron collector, an ion line, and a magnetic analyzer are located in the lower section of the facility. Like IMI-1 7-9, IMI-2 2-6 was also designed at the Budker Institute of Nuclear Physics for production of multicharge beams of gaseous and solid elements. In the EBS parameters, IMI-2 is intermediate between first-generation EBIS and those that can be used at acceleration complexes developed at the present time.
