A hybrid-PIC implementation in WarpX
May 2022 | R. Groenewald | Sherwood 2023 | Poster
Enable steady-state simulations of the FRC reactor to study global stability and particle transport.
RF dispersion relations in FRC geometries and HHFW regime
May 2022 | F. Ceccherini | Sherwood 2023 | Poster
HHFW in FRC configurations requires a hot-plasma approach that can be investigated through the RFP.
First results show that energy deposition is expected to depend
strongly on parallel refractive index.
First measurements of p11B fusion in a magnetically confined plasma
February 2023 | R. Magee | Nature Communications | Paper
Proton-boron (p11B) fusion is an attractive potential energy source but technically challenging to implement. Developing techniques to realize its potential requires first developing the experimental capability to produce p11B fusion…
Ion kinetic effects and instabilities in the plasma flow in the magnetic mirror
November 2022 | M. Jimenez | Physics of Plasmas | Paper
Kinetic effects in plasma flow due to a finite ion temperature and ion reflections in a converging–diverging magnetic nozzle are investigated
with collisionless quasineutral hybrid simulations with kinetic ions and isothermal Boltzmann electrons.
Non-singular computation of magnetic field created by 3D distributed plasma current density
October 2022 | S. Galkin | APS-DPP 2022 | Poster
Non-singular, accurate and “fast” (a few seconds on laptop with moderate dense 3D grid) method, based on numerical solution to a few 3D Poisson’s equations
Helicon waves in FRC configurations
October 2022 | F. Ceccherini | APS-DPP 2022 | Poster
The full-wave code RF_Pisa has been extended to model the so-called Helicon regime. These waves are whistler-type waves with a two-branch dispersion relation.
