The spectral distribution of coherently generated THz radiation is a favorable measure for the shape of the electron bunches. Today, THz spectrometers are bulky and costly. Here, the concept of an integrated on-chip semiconductor spectrometer being developed in a joint effort by HZDR and TU Dresden within the scope of the BMBF project InSEl is presented. This potentially low-cost and compact solution based on Schottky diode detectors, integrated on-chip THz antennas and filters fabricated in a commercial GaAs process will not exceed 5 mm in size replacing current single element THz detectors in the bunch compression monitors in the ELBE accelerator at HZDR. Covering the frequency range from 0.1 to 1.5 THz (and more in the future) with a resolution of 5 to 20 points, it could also be of interest for the longitudinal electron bunch diagnostic at other electron linacs such as FLUTE, BERLinPro, FLASH or the European X-FEL. Furthermore, the detector bandwidth in the GHz range supports the high repetition rates of superconducting radio frequency accelerators.
