in 1931, he received an engineering degree and got a job at the all-union electrotechnical institute.this is another revolution in his life. he becomes the head of the laboratory, knows perfectly the physics of x-ray radiation, and also knows methods for measuring this intensity. in 1939 there was another coup. wexler - doctor of sciences. at this time he was already working at the physics institute of the ussr academy of sciences. there he ends up in the atomic nuclear laboratory. wechsler's measuring instruments, created by him earlier, are perfectly suitable for experiments on the study of elementary particles of cosmic rays. with them began the epic with accelerators, cyclotrons, synchatrons and... one might ask, what does this have to do with these cosmic rays? it turns out that this is a unique natural a source of high ultra-high energies, making it possible to study the processes of transformation of elementary particles and their structure. many physicists were of the opinion that cosmic rays consist of electrons, either to confirm this or to disprove the hypothesis. the insti
