LASER SOURCE OF IONS WITH ACTIVE INJECTION SYSTEM Russian patent published in 2013 - IPC H01J37/08 

FIELD: electricity.

SUBSTANCE: invention is characterised by supply of electric voltage that varies in process of ion extraction to an accelerating electrode of an ion-optic system arranged between the output of a flight channel and another accelerating electrode, installed in the injection system at the output of the ion-optic system. The value of this voltage varies proportionately to variation of the longitudinal component of the particle pressure pulse, which arises in laser plasma in the area in front of the injection system electrodes. There is also supply of permanent electric voltage for ion acceleration provided to the accelerating electrode of the injection system installed at the output of the ion-optic system.

EFFECT: reduced spread of angular divergence of an ion beam envelope in process of ion extraction, which helps to reduce the value of efficient emittance of this beam at the output of the laser source of ions with an active system of injection, and increased capturing of ions generated by laser sources of ions.
