DESY will use a dielectric loaded waveguide to accelerate electron bunches up to 15 MeV.
Such a linac will be powered by a narrowband multicycle THz-pulse with a central frequency
of 300 GHz. In this paper we focus on the reflection of the excited field at a pinhole, on the
optimization of the bunch injection time and on the bunch dynamics in the acceleration
process. The linac excitation by the THz-pulse and the bunch acceleration in the excited …
