The paper describes the features of the design of an experimental bench for studying a discharge in a highly inhomogeneous gas stream, supported by focused radiation in the terahertz range. The setup was created at the user station of the Novosibirsk free-electron laser. The optical scheme that allows one to achieve electric field strength in the wave of up to 1 MV/cm is described. The results of the first experiments on the study of a breakdown in a focused radiation beam with a frequency of 2.3 THz are described.
