| Abstract |
While the axial injection into the cyclotron, the beam is turned from axial direction into median plane by means of inflector. Commonly used type of inflector is an electrostatic spiral inflector. The spiral inflector is easy to handle and has a good beam transmission factor. On the other hand, the negative feature of spiral inflector is the beam vertical divergence at the exit of inflector. It leads to increasing of beam vertical dimension and aperture losses at the first orbits. The methods of compensation of the beam vertical divergence at the inflector exit are considered at present report. This methods are used at FLNR JINR cyclotrons and give a good results in transmission factor, beam quality and operation modes.
