Generation of subpicosecond X-ray pulses using RF orbit deflection

A technique is proposed for producing high average intensity X-ray radiatio n from a storage ring for studies of the ultrafast phenomena on a subpicose cond time scale. Two RF cavity accelerating structures excited in the E-110 mode can be installed in a storage ring to create vertical displacements o f electrons correlated with their longitudinal position in the bunch. The m agnitude of these displacements can be sufficient for the X-ray radiation o f the electron bunch between accelerating structures to be viewed as produc ed by a large number of independent sources, each of a subpicosecond durati on.
