Abstract
Neutron production rates using laser-accelerated protons from highenergy single-shot laser (giant pulse laser) and low-energy high-repetition tabletop laser systems are compared. With the VULCAN giant pulse laser, more than 109 neutrons per shot were produced in a nanosecond pulse through (p,xn) reactions with lead. In contrast, a current state-of-the-art tabletop laser theoretically can produce 106 to 107 neutrons per second in repetitional nanosecond pulses. It is estimated that next-generation tabletop lasers currently under construction will be capable of producing nanosecond neutron pulses at a rate of 1010 neutrons per second.
