Realistic 3D Tracking Methods Through Electrostatic Elements for Low Energy Beamlines | |
|

| In 2020 transfer lines will begin transporting extremely low energy (100 keV) antiproton beams from the Extra Low Energy Antiproton (ELENA) ring to the antimatter experiments at CERN. To achieve this, and obtain the greatest efficiency, transfer lines will be based on electrostatic optics. Unfortunately, only a small amount of simulation codes allow realistic and flexible implementation of such elements. In this contribution, methods for accurately creating and tracking through electrostatic optical elements are presented, utilising a combination of finite element methods with both a modified version of G4Beamline and BMAD. A range of approaches to modelling the electrostatic elements were explored, ranging from simple field expressions, to the complex field maps used in the final model. An investigation into the achievable beam quality at one of the experiments is presented. Realistic beam distributions obtained via tracking around ELENA in the presence of collective effects and electron cooling will be propagated along the optimised 3D transfer lines models. | ||
