Title:
LASER ACTIVATED MAGNETIC FIELD MANIPULATION OF LASER DRIVEN ION BEAMS
Document Type and Number:
WIPO Patent Application WO/2013/114351
Kind Code:
A3
Abstract:
A system for generating pulses of charged particles, comprising a high intensity pulsed laser emitting laser pulses which, when impacting a target, generate pulses of charged particles. The particles passes through an electromagnet energized by a low inductance current feed incorporating a light activated switch to turn the energizing current on and off. Part of the light of the laser pulse is directed onto the light activated switch, such that the magnetic field is optically synchronized with the generated pulses of charged particles. This enables energizing the magnet only during passage of the pulses, such that it is lighter and more energy efficient than prior art systems using CW electromagnets. Synchronization also enables selection of charged particles having a predetermined range of particle energy, by timing activation of the magnetic field such that it diverts onto a selected beam path only the particles having the predetermined range of energies.
