BUSCADOR RECOLECTA

Data captured by ATD during the PETE device development within the H2020 E.T.PACK project execution

We performed a cross-validation and a benchmarking analysis of five electrodynamic tether (EDT) simulators developed by independent research groups: BETsMA, DYNATETHER (DYNAT), EDTSim, FLEX, and TeMPEST. It is a multi-institutional and multi-national project since the codes were developed at UC3M in Spain, at YU in Canada, at JAXA in Japan, at UNIPD in Italy, and at PSU in the USA, respectively. We tested and compared the implementation of the orbital propagators, the environmental models, and the electrical and dynamical models for the EDT.

Software to explore the plasma structure around a cylindrical emissive probe using Orbital Motion Theory (OMT).

The goal of the data is showing the structure of the ion distribution function around a negatively polarized Langmuir probe with an elliptical cross section of eccentricity e_p. For e_p= 0 (cylindrical probe), the orbits of the ions are regular (integrable configuration) and the boundary that separates trapped and non-trapped ions in velocity space is a smooth curve. For e_p≠ 0, some orbits are chaotic (non-integrable configuration) and the boundary that separates trapped and non-trapped ions in velocity space has a fractal structure. The data also highlights the role of the numerical parameter N_tr, which control the number of loops around the probe that an ion should perform to be considered as trapped by the Vlasov-Poisson solver.
