Particle accelerators with high intensity beams require non-interceptive diagnostics because any interceptive tools can be damaged or can perturb the beam during measurements. At LEDA group, the use of tomography to develop a non-interceptive transverse profile monitor is developed. Transverse spatial density of the beam from the Source d’Ions Légers de Haute Intensité (SILHI) beam line was reconstructed non-destructively and non-interceptively via tomography technique. Six cameras, positioned at six different directions around the beam, were aligned with respect to the beam axis and were installed to obtain the image of the emitted light due to the beam-residual gas interaction. A combination of optical profile measurements with tomography provides a significant contribution on the development of beam profile monitors for particle accelerator beams.
