For this purpose, Almaz-2M diagnostics were carried out. She found the need to ensure stable operation of the electron gun modulator and modernize the accelerator systems synchronization device. Repair and checkout of the electron gun modulator consisted of upgrading the 12 kV rectifier to obtain the additional ability to control the slope of the front of the injected electron accelerating pulses. The reliability of the accelerator electron gun modulator has been increased due to the transition of its 12 kV power source from a vacuum to a modern semiconductor element base. Using an MI-30 magnetron installed in the klystron master oscillator, a waveguide storage calorimeter based on an LM-35 temperature sensor was tested and tested; in the energy range from 3 to 88 J, a reading difference of 1.5°C was obtained. An analysis of electron sources used for accelerating lattice and flat dielectric chip structures was carried out. For comparison, the main operating characteristics of laser plasma accelerators (LPAs) and photoemitters are presented. More advanced versions of electron accelerator systems on lattice and flat chip structures with LPA injectors as sources of electrons are presented in comparison with previously discussed projects. Requirements for the laser source are formulated to ensure efficient operation of the LPA injector by meeting operating conditions approaching the λ3 mode. In the context of the above, the fulfillment of these conditions is presented through the use of adaptive optics and the creation of a regime for excitation of a plasma wake wave, in which the dynamics of electron capture was carried out in an inhomogeneous plasma. The parameters of an optimized version of the LPP injector for laser accelerators with lattice and flat chip structures are presented.
