At the 1.5-GeV electron storage ring DELTA, operated by the TU Dortmund University, a broadband source for coherently emitted THz radiation was commissioned in 2011. The THz generation is based on the interaction of titanium-sapphire laser pulses and a single electron bunch in the storage ring. Recently, the laser setup was extended using a temporal modulation of the laser pulses to produce narrowband radiation which can be easily tuned to the desired THz or sub-THz frequency. One application is the measurement of the spectral sensitivity of THz detectors, such as a novel single-shot on-chip spectrometer developed by TU Dresden. A first characterization of the new source and a comparison of different THz detectors are presented.
