In order to shrink the size of the accelerators one possible way is to go to higher frequencies e.g. THz regime. We pursue such method in the AXSIS project (Attosecond X-ray Science: Imaging and Spectroscopy). Two laser driven THz electron injectors have been designed to be used as the gun in THz accelerating structures: First, a broadband multilayer structure which is capable of accelerating the electrons from rest up to 1.5MeV kinetic energy using 2mJ single cycle of THz signal. The second design is a four cell ormal conducting cavity which is actually a narrow-band component and needs about 300 THz cycles with an energy of 1.1 mJ to accelerate the eectrons from rest up to 250 keV. Both structures operate at 300 GHz.
