Estimation of erosion phenomena within helicon plasma sources through a steady-state explicit analytical model

Autor: Juan I. Del Valle, Víctor H. Granados, Franklin R. Chang Díaz

Publikováno v: Frontiers in Physics, Vol 10 (2022)

Helicon plasma sources produce high-density discharges without the need of electrodes in direct contact with the plasma, which is thought to provide them with long operational lifetimes. An explicit steady-state analytical model is described with the

Plasma-Surface Interactions Within Helicon Plasma Sources

Autor: Juan I. Del Valle, Franklin R. Chang Diaz, Víctor H. Granados

Publikováno v: Frontiers in Physics, Vol 10 (2022)

Helicon plasma sources do not require electrodes or grids directly immersed in the plasma, and also present an axial magnetic field confining the plasma discharge. These factors are believed to provide them with long operational lifetimes because of

Solar electric propulsion for human mars missions

Autor: Franklin R. Chang Díaz, Les Johnson, William G. Johnson, Giancarlo Genta, John A. Carr, P. Federica Maffione

Publikováno v: Acta Astronautica. 160:183-194

While solar electric propulsion (SEP) is being widely considered for cargo transport to Mars, its value for propelling fast human missions is often viewed as marginal. This conclusion is driven by the high electric power requirement (multi megawatts)
