A multi-channel plate with a phosphor screen was purchased. Samples of photoemission cathodes have been created. In the circuit of the master generator, a pump laser is installed and its settings are carried out. The vacuum chamber was installed and started. A model of a high-voltage power supply unit has been created, another scheme is under development. Numerical simulation by the LCODE program found the parameters under which the same accelerating field is maintained in the nonlinear regime of wake wave overturning for a bunch of positrons during a significant part of its acceleration time while it is simultaneously in the focusing field. Based on the developed linear theory of the generation of the wake field by electron bunches injected with a offset relative to the axis into the plasma-dielectric waveguide and numerical simulations, it is shown that the presence of plasma leads to the focusing of driver and accelerated bunches.
