Towards stable coherent undulator radiation based on Steady State Microbunching SSMB

We report on correlating THz bursting signatures from longitudinal compressed bunches for emitting coherent synchrotron radiation (CSR) with signals from coherent undulator pulses generated by the mechanism of steady state microbunching (SSMB). There is clear evidence, that the state of the electron bunch in phase-space and the effective emission of coherent undulator radiation can be correlated and thereby optimized.
