Description
Tomographic phase space reconstruction method based on the beam dynamics code Travel is applied to the RAON linear accelerator in the LEBT and in the MEBT. Due to the low beam energy and the two dipoles in the LEBT, it matters to include the space charge effect and the second-order effects of dipoles. When compared with the Allison scanner emittance data in the LEBT, the phase space tomography demonstrates a very good agreement even though the actual beam is far from Gaussian. The method of fitting rms beam sizes of wire scanners is also compared with the phase space tomography method. The method of fitting rms beam sizes produces a very good agreement when the actual beam is close to Gaussian, because the beam size fitting method uses Gaussian input beam in the simulation.
