DEVICE FOR STUDYING CHARACTERISTICS OF ION FLOW OF PLASMA, CREATED BY PULSE SOURCE, IN PARTICULAR BY CO LASER Russian patent published in 2018 - IPC H01J47/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement means in plasma physics and charged particle physics. Device for studying the plasma produced by laser pulses consists of a vacuum chamber with an irradiated target, a time-of-flight tube, an electrostatic ion energy spectrum analyzer, a charged particle detector, which is used as a secondary electronic multiplier (SEM), a laser pulse sensor and a two-channel oscilloscope. Time-of-flight tube is completed with an insert of known length, with which additional calibration measurements are carried out, the result of which is the determination of the ion flight length and the time binding of the times of ion emission from the target to the laser pulse.

EFFECT: increase in the accuracy of determination of the flight length, eliminating the systematic error in measuring the arrival time and ion energy, as well as the possibility of direct measurement of the times of ion emission of different energy and charge from the plasma at the scale of the duration of the laser pulse due to an increase in the accuracy of the restoration of the energy spectra of ion dispersion.
