FIRSOV, G.O. TSVETKOV Taking into account the disadvantages of the electrostatic system for the extraction of photoions currently used in laser isotope separation systems, alternative possibilities are considered. The most promising is the extraction system using the J × B drift of the plasma bunch as a whole without charge separation. An increase in the pulsed current in the electrode inductor to 1,5 kA in 10 μs was experimentally obtained, which corresponds to the value of the transverse horizontal component of the magnetic field induction in the operation volume of the laser isotope separation system of 11 mT at the rate of rise of the horizontal component of 4000 T/s. This means that, on the basis of a modern element base with the use of semiconductor devices with increased switching and frequency characteristics, it is possible to create the necessary magnetic fields for the extraction of photoions based on the J × B drift.
