Tomographic phase space reconstruction during rebucketing in the Relativistic Heavy Ion Collider

Longitudinal phase space tomography has evolved into a powerful diagnostic tool in the particle accelerator domain. A computer code has been developed in order to visualize dynamic effects and measure machine parameters in longitudinal phase space. This code is capable of dealing with turn-by-turn parameter changes, for example, during rf rebucketing when the bunch is rotated in longitudinal phase space to minimize the bunch length. We describe the reconstruction code and show its application as a diagnostic tool for rebucketing in the Relativistic Heavy Ion Collider.
