The transverse instability of clumps upon excitation of a large accelerating wake field in a dense plasma in the nonlinear regime by two laser pulses and self-injected accelerated electron clumps was investigated. Theoretical acceleration and transverse dynamics of relativistic charged particles injected asymmetrically with respect to height in multi-section plasma-dielectric structures were investigated. Recommendations are given for the creation of plasma-dielectric electron/positron wake accelerators and suppression of transverse instability of accelerated clumps. Test experiments on electron acceleration on chip structures were conducted. Acceleration rates depending on the type of chip structure, analysis of conditions affecting acceleration rates and recommendations for increasing acceleration rates were studied. A comparison is made with the results of other authors working on DLA problems.
