The micro-bunching instability causes the formation of time-varying sub-structures in the longitudinal phase space leading to fluctuations and strong bursts in the observed coherent synchrotron radiation (CSR) in the terahertz (THz) frequency range. These fluctuations can be detected simultaneously for each individual bunch in a multi-bunch environment using fast THz detectors combined with the KAPTURE readout system. This combination allows us to study the possibility of multi-bunch effects on the characteristic bursting behavior of the micro-bunch instability. Additionally the spectral information of the CSR contains valuable information about the bunch length, shape and sub-structures. This can be studied with a spectrometer setup consisting of 4 ultra-fast THz detectors, sensitive in different frequency bands.
