Ionization by electron impacts and ionization potential depression
Djamel Benredjem, Jean-Christophe Pain, Annette Calisti +1
We calculate the cross-section of ionization by free-electron impacts in high or moderate density plasmas. We show that the so-called ionization potential depression (IPD) strongly…
Plasma density effects on the electron impact ionization
Djamel Benredjem, Jean-Christophe Pain, Annette Calisti +1
We present new results on the ionization by electron impacts in a dense plasma. We are interested in the density effect known as the ionization potential depression and in its role…
Structural phase transitions in multipole traps
Mathieu Marciante, C. Champenois, Annette Calisti +1
A small number of laser-cooled ions trapped in a linear radiofrequency multipole trap forms a hollow tube structure. We have studied, by means of molecular dynamics simulations, th…
Parallel ion strings in linear multipole traps
Mathieu Marciante, Caroline Champenois, J. Pedregosa-Gutierrez +2
Additional radio-frequency (rf) potentials applied to linear multipole traps create extra field nodes in the radial plane which allow one to confine single ions, or strings of ions…
Ion dynamics in a linear radio-frequency trap with a single cooling laser
Mathieu Marciante, Caroline Champenois, Annette Calisti +2
We analyse the possibility of cooling ions with a single laser beam, due to the coupling between the three components of their motion induced by the Coulomb interaction. For this p…
