摘要:
A preliminary result is given for the transverse and longitudinal root mean square divergence angles for an ion beam traversing a sample finite slot accelerator design. The result is obtained using a finite element code to achieve a three‐dimensional explicit solution for the extraction sheath resulting from the solution of the Poisson Vlasov equation. This is the first three‐dimensional explicit sheath solution for a possible neutral beam accelerator electrode design.
