| Abstract | The goal of tomography is to reconstruct a higher dimensional distribution from a series of projections measured in a lower dimensional subspace. In the absence of large number of projections, the maximum entropy algorithm can reconstruct a distribution that maximizes the entropy and simultaneously reproduce all the measured projections exactly. The MENT algorithm has been applied to the reconstruction of the transverse and longitudinal phase space distributions at particle accelerators. Only one-dimensinonal intensity profiles of different beam transfer matrices have to be measured. The article mainly completed the code for the tomographic reconstruction of the longitudinal phase space where non-linear transformations have to be taken into account, and finally introduced the test result of the real data taken from accelerator in triumf for transverse tomography. | |||||
