Abstract

We present simulations of the acceleration and compression of electron bunches for megaelectronvolt ultrafast electron diffraction (MeV-UED) experiments planned at the National Centre for Nuclear Research in Poland (NCBJ). This compact MeV-UED facility, currently under construction, will consist of an electron photoinjector, a superconducting accelerating HZDR/RI-type cryomodule housing two TESLA cavities, and experimental chambers. Simulations demonstrated the feasibility of producing short electron bunches with a duration of a few femtoseconds for electron beam energies ranging from 2 to 5 MeV.
