PULSE CURRENT LENS TO FORM HIGH-INTENSITY BEAMS OF CHARGED PARTICLES Russian patent published in 2001 - IPC

FIELD: acceleration equipment. SUBSTANCE: pulse current lens is made of central forward and outer backward conductors of electric current arranged coaxially. Central conductor is fabricated in the form of either thin-walled tubes inserted coaxially one into another and connected in parallel electrically or comes in the form of bunch of thin-walled tubes connected in parallel electrically and placed with minimal deviation from axial symmetry. Manufacture of central conductor in such form contributes to formation of pulse current focusing element from light, strong materials with quasi-linear magnetic field conducting electric current well. EFFECT: formation of focusing element from light, strong materials. 5 dwg
