Аннотация

An investigation into the microbunching instability at Diamond Light Source has recently been conducted. Beyond the instability threshold, the longitudinal distribution of the bunch starts filamenting. As a result, the bunch emits bursts of coherent synchrotron radiation with wavelengths shorter than the bunch length. The operating conditions for producing the instability include both standard optics, and low-alpha optics, where the bunch length can be shortened to a few picoseconds. A Michelson interferometer has been designed and installed utilising a silicon crystal wafer beamsplitter. Large bandwidth, room temperature pyroelectric detectors and low-noise, fast-response Schottky Barrier diode detectors have been employed to measure the interferograms. In this paper, we describe the observed results and calculated spectral content.
