Beam Transverse Phase Space Portrait Tomography at the High-Intensity Linear Accelerator of Hydrogen Ions.

An implementation of the tomographic reconstruction of the beam transverse phase space portrait based on fast simultaneous algebraic reconstruction technique, which is rarely used in accelerator physics, is presented. The developed diagnostic procedure has been performed at the INR RAS high-intensity linear accelerator of hydrogen ions and has been experimentally tested in the beam energy range from several tens to several hundred MeV. The applicability of data from different beam-profile monitors is shown, and the tomographic method is compared to the standard transverse profiles method. A procedure for verifying reconstructed data is proposed for use in transfer matrix codes, and examples of its use in case of significantly nonelliptical phase portraits are presented.
