FIELD: physics.
SUBSTANCE: invention relates to the field of forming charged particles under atmospheric pressure and can be used in the scientific activity, in medicine, in technological processes, in secondary ion mass spectrometry under atmospheric pressure. The apparatus for receiving and transporting a proton beam provides a possibility of obtaining a stable proton beam during electrospraying without forming large droplets in the course of the entire spraying process under normal conditions, without resorting to gas heating. Characteristics of the apparatus include the use of a system for transporting and separating protons under atmospheric pressure when applying meshless diaphragms. Electrospraying of solutions with dynamic division of the flow of the solution and removal of excess solution from the spraying area are applied to implement the apparatus. Protons are extracted from the top of the meniscus of an electrolyte located in a non-homogeneous constant electric field. The proton extraction mode is stable for the entire duration of the electrolyte entering the meniscus. The use of the system for transporting protons provides a possibility of transforming the diverging initial beam into a parallel beam with an increase in the current density on the axis of the apparatus.
EFFECT: possibility of obtaining a reproducible long-term stable proton current under atmospheric pressure in a benchtop implementation.
