Beam loss is a critical issue to be avoid in high power proton accelerators due to machine protection from radiation. Nonlinear processes add higher order moments and cause halo and tail structures to a beam, resulting in beam losses. Hence it becomes more important to characterize beams for high power accelerators. Conventional beam diagnostic methods can measure only approximate elliptical features of a beam and are not suitable for high power beams. Tomography method reconstructs a multidimensional distribution from its lower-dimensional projections. We used this method to reconstruct the 4D transverse (x, x’, y, y’) phase space distribution of the beam from the accelerator at KOMAC (Korea Multipurpose Accelerator Complex). RFQ BTS (Radio Frequency Quadrupole Beam Test System) was constructed and commissioned in 2022. In the BTS, we performed tomography experiements and obtained preliminary results on 4D transverse phase space beam distribution. We also have applied the tomography measurement techniques to the 100 MeV proton linac. In this paper, we describe the tomography measurement system and present the preliminary results obtained from the BTS and the 100 MeV proton linac.
