Description
SEISM is a unique ECR ion source operating at a frequency of $60~\textsf{GHz}$. The prototype is based on a simple magnetic geometry, the CUSP, allowing the use of polyhelix coils (developed with LNCMI, Grenoble) to generate the closed ECR surface at $2.1~\textsf{T}$. The plasma is sustained by a high intensity HF pulse (up to $300~\textsf{kW}$). Previous experiments at LNCMI have successfully demonstrated the establishment of the nominal magnetic field and the extraction of ion beams with a current density of up to ~ $1\textsf{A }/ \textsf{cm}^{2}$. The presence of "afterglow" peaks was also observed, proving the existence of ion confinement in a CUSP ECR source. An experimental campaign will be carried out in 2021 using a new transport line designed to improve the transmission of the beam to the new detectors. Recent experimental results as well as short and long-term research plans should be presented to transform this high current density into a high intensity ion beam that can be used for accelerators of the future.
