FIELD: instrument engineering.
SUBSTANCE: ion source can be used for making a design of as source of radial divergent ion flow of organic matters. Ion emitter with diameter of D is provided with casing, which is installed in axial to active surface if ion source. Ion emitter has cylindrical side surface with diameter D1>D and flat edge surface, conjugated with active surface of ion emitter along diameter D and cylindrical side surface of casing along diameter D1. One edge of electrode for controlling ion current is turned to ion emitter and input coupling, having channel with diameter d, is hermetically attached to second edge of electrode for controlling ion current.
EFFECT: widened functional abilities.
