Work Context

The LPGP and particularly the Theory and Modeling of Plasmas – Discharge and Surface (TMP-DS) team develop and study numerous types of plasma sources, most of them being low pressure -high density. These sources are widely used to produce charged particles beams usually exploited for particle accelerators, synchrotron, etc. Generally, the energy transferred to the particles comes from an electrostatic arrangement of grids, followed by several electro-magnets acting on the shape of the beam, correcting aberrations, etc.
The topic proposed here concerns the characterization of the plasma and the study of the electro-magnetic optics for better understanding the source operation and the beam features. These results will be compared with the prediction given by the numerical models available in the team. Precisely, the focus will be on the beam structure and the correlations between the electromagnetic structure and the final beam shape, aiming the model validation.
During the first stage of the project, a plasma source will be used to generate either an electron beam or an ion beam. This study will concern the source characterization and the beams, in terms of intensity, divergence, etc.
In the second stage, the existing structure will be optimized to improve the beam quality depending on the mass and the charge (for ions) and the acceleration energy for electrons.

Constraints and risks

Confidentiality required.
