EOS and coherent radiation based diagnostics of sub-psec electron bunches are longitudinal diagnostics adopted for FERMI and other 4th generation light sources. The performance of both kind of diagnostics depends on the material properties in the THz spectral range. There is a need to characterise the transmission of windows materials and to understand the absolute efficiency of electro-optic detectors. This requirement for absolute EO efficiency is particularly important given observed variations between individual crystals with nominal identical specifications. In this paper we report measurements with THz pulses produced with photoconductive emitters. Our main goal was the characterization of EO crystals such as ZnTe and GaP for EOS and THz windows materials and humidity absorption. Good agreement is found for EO between experimental results and theoretical calculations concerning temporal resolution. |
