The article presents the investigation of the operation modes of the accelerator with the anode layer. The experiments revealed that there exists such a range of the magnetic field strength in the accelerator channel of the accelerators with the anode layer, in which the accelerator operates in the so-called diffusive mode, and there is an acceleration mode beyond this range. Through the use of the ion current collector we have observed a disintegration of the beam during the transition into the diffusive mode. The article describes an installation used for conducting the experiments, specifies the equipment it consists of, and outlines the essence of the experiments. We deduce that the transition from the acceleration mode into the diffusive mode is allegedly associated with the buildup of the ion beam positive space charge.
