Dense short electron bunches produced by state-of-the-art photoinjector-based accelerators are used to create sources of powerful electromagnetic pulses of terahertz frequency range based on spontaneous coherent emission by these bunches. However, there is a problem of stabilizing the phase dimension of a bunch along the space of electron wave interaction. In this work, two means of such stabilization are considered that are based on using the intrinsic electromagnetic fields (quasi-static and radiation) of bunches.
