Longitudinal Tomography of Ion Bunches in the JINR Superconducting Booster Synchrotron

Methods for processing a digital signal proportional to the longitudinal intensity of ions in bunches during their acceleration in a synchrotron are discussed. Computer tomography is employed to reconstruct the longitudinal 2D ion distribution function in a bunch using data on its longitudinal profiles that depend on the bunch length and the synchrotron motion of particles. Presented are examples of tomographic reconstruction of the longitudinal distribution function of xenon ions in the JINR superconducting booster synchrotron prior to extraction (after acceleration) and on the injection plateau also with the activated electron cooling system.
