If the parameters of the proton beam change (energy and current of the beam, the parameters of the ion-optical system, the parameters of the ion source) - accordingly the conditions for the beam transportation change (its size, angular divergence, and position relative to the axis of the accelerator). For optimal conduction of the beam along the beam line, two-dimensional tomography of the beam can be used: using a cooled diaphragm with a diameter of several millimeters installed on a vacuum three-dimensional motion input and a Faraday cup, fast chord measurements are carried out, on the basis of which the beam profile is restored. The beam profile obtained by this way is somewhat different from the profile obtained by measuring the phase portrait of the beam using a wire scanner. The advantage of this method is a relatively short time to restore the profile, depending on the diameter of the cooled diaphragm.
