Subject of study. This study investigates the precise aiming of radiation from multichannel laser systems at a target in experiments involving the conversion of laser radiation into X-ray radiation, plasma heating and compression physics, and other phenomena resulting from the interaction of high-power radiation with matter. Aim of study. The aim of the study is to implement a method and develop equipment that enables the automatic aiming of laser beams from multichannel laser systems at a target under cubic irradiation symmetry, with detection of the alignment radiation from the multichannel laser. Method. The method involves solving the problem of aiming the working radiation at the target using an optoelectronic system prior to conducting physical experiments on multichannel laser facilities. This is achieved by employing alignment radiation generated in continuous mode and detecting it at specified locations on the target. Main results. An optoelectronic system has been developed for aiming at a target while detecting the radiation used for the alignment of a multichannel laser. The proposed aiming method and its implementation using the developed equipment allow the convergence and focusing of laser-channel beams into specified areas of up to 20 µm in size on the edges of the target simulator. The system also enables control over the aiming accuracy of each individual beam, as well as of multiple beams simultaneously, within a defined spatial region. Practical significance. The results contribute to improving the speed and precision of laser-beam alignment in multichannel laser systems. The developed aiming system enables verification of the absence of misalignment in previously adjusted channels and allows simultaneous monitoring of alignment accuracy during the setup of the current channel. This offers a comprehensive solution for automating the full range of alignment tasks encountered in preparing a target for physical experiments on multichannel laser facilities. These tasks include determining, fixing, and reproducing the coordinates of the center of a spherical target chamber; converging and focusing the laser-channel beams at defined points in the central region of the chamber; and aligning the target itself.
