Duration of coherent synchrotron radiation pulses accessed via time-resolving and correlation techniques

Coherent synchrotron radiation (CSR) is emitted from bunches of relativistic electrons in a storage ring. The CSR spectrum depends on the shape of the electron bunch from which the CSR radiation is emitted. Instantaneous monitoring of the form and duration of the field transients in CSR pulses is important for applications in pump-probe studies of carrier dynamics in semiconductors and superconductors,where the required excitation must be simultaneously unipolar and much shorter than the expected relaxation time. Here we use two types of ultra-fast detectors, Schottky diodes and superconducting microbridges, to evaluate the duration of transient field-oscillations in CSR pulses under stable average intensity of the CSR source by means of time-resolving and field-correlation techniques. We show that both methods deliver close results.
