Self-consistent beams
A Vlasov iteration of field solve, trajectory tracing and space-charge deposition, in planar or cylindrical (x, r) geometry.
beamtracer
Steady ion beams in a self-consistent field. Extraction of positive or negative ions, transport through electrodes and solenoids, charge changes in a neutralizer.
What it does
Section titled “What it does”Extraction from a plasma
Boltzmann plasma electrons for positive ions, Boltzmann plasma ions for negative ions, which form the meniscus.
Charge changes
Every trajectory carries the fractions of its particles in each charge state, on a gas or a plasma, and couples to a neutralizer model.
CPU and GPU kernels
The field gather and the charge deposit as Pyccel, NumPy, CUDA and Metal kernels through cunumpy.
