Autor: A. Le Ru, G. Ibarcq, M.- C. Boniface, A. Baussart, S. Muños, M. Chabaud

Publikováno v: Plant Methods, Vol 17, Iss 1, Pp 1-14 (2021)

Abstract Background The parasitic plant Orobanche cumana is one of the most important threats to sunflower crops in Europe. Resistant sunflower varieties have been developed, but new O. cumana races have evolved and have overcome introgressed resista

Experimental characterization of ID-Hall, a double stage Hall thruster with an inductive ionization stage

Autor: A. Martín Ortega, C. Boniface, A. Guglielmi, Jean-Pierre Boeuf, F. Gaboriau

Publikováno v: Physics of Plasmas
Physics of Plasmas, American Institute of Physics, 2020, 27 (2), pp.023518. ⟨10.1063/1.5140241⟩

We present experimental results on the characterization of ID-Hall, a double stage Hall thruster with an inductively coupled magnetized ionization stage. This first experimental prototype of ID-Hall operates in a low power regime, typically below 400

ID-HALL, a new double stage Hall thruster design. II. Experimental characterization of the inductive ionization source

Autor: Laurent Liard, F. Gaboriau, Loic Dubois, C. Boniface, Jean-Pierre Boeuf

Publikováno v: Physics of Plasmas
Physics of Plasmas, American Institute of Physics, 2018, 25 (9), pp.093504. ⟨10.1063/1.5043355⟩

Double Stage Hall Thrusters (DSHTs) are designed to allow separate control of ionization and ion acceleration by adding a plasma source (ionization stage) upstream of the magnetic field barrier (acceleration stage) of a standard Hall thruster. In thi

ID-HALL, a new double stage Hall thruster design. I. Principle and hybrid model of ID-HALL

Autor: Carole Henaux, Laurent Liard, Loic Dubois, Laurent Garrigues, Jean-Pierre Boeuf, St 'ephane Mazouffre, G. J. M. Hagelaar, F. Gaboriau, Dominique Harribey, C. Boniface

Publikováno v: Physics of Plasmas
Physics of Plasmas, American Institute of Physics, 2018, 25 (9), pp.093503. ⟨10.1063/1.5043354⟩

International audience; In Hall thrusters, ions are extracted from a quasineutral plasma by the electric field induced by the local drop of electron conductivity associated with the presence of a magnetic barrier. Since the electric field is used bot
