Dedicated optics with extremely short electron bunches enable synchrotronlight sources to generate intense coherent THz radiation. The high degree ofspatial compression in this so-called low-alpha optics entails a complexlongitudinal dynamics of the electron bunches, which can be probed studying thefluctuations in the emitted terahertz radiation caused by the micro-bunchinginstability ("bursting"). This article presents a "quasi-instantaneous" methodfor measuring the bursting characteristics by simultaneously collecting andevaluating the information from all bunches in a multi-bunch fill, reducing themeasurement time from hours to seconds. This speed-up allows systematic studiesof the bursting characteristics for various accelerator settings within asingle fill of the machine, enabling a comprehensive comparison of the measuredbursting thresholds with theoretical predictions by the bunched-beam theory.This paper introduces the method and presents first results obtained at theANKA synchrotron radiation facility.
