A Precise 3D Beam Dynamics Model of the PSI Injector II | |
|
||
| A precise beam dynamics model of the PSI Injector II operating at 2.2 mA is presented, including 3D space charge, and the collimation system. A particle distribution with an intensity of 9.5 mA (DC) is injected into the central region, shaped by a sophisticated collimator system. This defines the initial condition for the subsequent formation of a round stationary bunch. The intensity limits are estimated based on this model, additionally supported by an idealised collimator model and measurements. The production configuration current scales to the power of four with the beam size setting the limit to approximately 3 mA. Further analysis of an upgraded configuration (adding two new cavities) suggests that intensities of 5 mA could be produced with an adjusted collimation scheme. The precise beam dynamics model is based on the OPAL (Object Oriented Parallel Accelerator Library) simulation code, a tool for charged-particle optics calculations in large accelerator structures and beam lines including 3D space charge. | ||
