Application of a low-energy electron beam as a tool of nondestructive diagnostics of intense charged-particle beams

A new diagnostic instrument intended for measuring the parameters of intense bunches, detecting radiation fields, and performing tomography of intense ion beams is described. The operating principle of the device and the basic scheme of arrangement of its elements are described. The results of simulation of a EBP for several problems are presented. To reconstruct the longitudinal charge-distribution function, the effect detection error of the testing beam on the accuracy of the proposed method is considered. Depending on the problem to be solved, several design versions of the instrument are proposed, which are optimized for diagnosing beams of S-range linear accelerators, detecting radiation fields, studying bunches of superhigh intensity, performing tomography of intense proton beams, and operating in cyclic accelerators.
