''Hollow cathode'' gun optics
No full textThe generation of an electron beam by a hollow cathode gun in a cusp magnetic field is discussed. Such a gun is proposed for an electron cooling device without toroids. In a section with a homogeneous magnetic field, this beam experiences a disturbance region near the axis where the electron temperature becomes higher. The main purpose of the article is to define conditions for generating the beam so as to restrict the extent of this region as much as possible. It is shown that a state with a virtual cathode in the vicinity of the zero magnetic field point is the most suitable for this aim. The experimental and essential analytical results are presented
PROTOTYPE OF AN ELECTRON COOLING DEVICE WITHOUT BENDING MAGNETS
No full textThe technical solution of a prototype of an electron cooling device without bending magnets is presented. The electron beam with a current of up to 1 A is formed in a ''hollow'' gun, accelerated up to 20 kV and its energy is recovered in a ''hollow'' collector with a current loss of less than 10-4. Preliminary beam quality tests are described
