We propose a scheme to generate high-flux, short-burst {gamma}-ray radiation and its application for generating ultrashort positron beams. The intense {gamma}-ray bursts are generated from short laser pulses scattering off high-energy electron beams in a storage ring. The {gamma}-ray bursts are then used to irradiate thin metal targets to generate the positron beams via pair production. Using the example of the Advanced Photon Source storage ring, more than 10{sup 7} positrons/s in 1 ps pulses at energies of a few MeV can be generated.
