Heating rate in a linear quadrupole trap
Adrien Poindron, Jofre Pedregosa-Gutierrez, Caroline Champenois
In radio-frequency trap, the temperature of ion ensembles converges towards a hot equilibrium due to radio-frequency heating. This effect is detrimental to the stability of trapped…
Thermal bistability in laser-cooled trapped ions
Adrien Poindron, Jofre Pedregosa-Gutierrez, Caroline Champenois
The non-linear dynamics of large ion clouds ( ions) trapped in radio-frequency traps and coupled to laser-cooling give rise to a bistable behaviour of the temperature.…
Realisation of homogeneous ion chain using surface traps
J. Pedregosa-Gutierrez, M. Mukherjee
In a Radio-Frequency linear ion trap, 1D ion chains are routinely generated in laboratories around the world. They present a non-homogenous ion density along the chain. The possibi…
Direct N-Body problem optimisation using the AVX-512 instruction set
Jofre Pedregosa-Gutierrez, Jim Dempsey
The integration of the equations of motion of N interacting particles, represents a classical problem in many branches of physics and chemistry. The direct N-body problem is at the…
Non-destructive detection of large molecules without mass limitation
Adrien Poindron, Jofre Pedregosa-Gutierrez, Christophe Jouvet +2
The problem for molecular identification knows many solutions which include mass spectrometers whose mass sensitivity depends on the performance of the detector involved. The purpo…
An analytical approach to symmetry breaking in multipole RF-traps
Marylise Marchenay, Jofre Pedregosa-Gutierrez, Martina Knoop +2
Radio-frequency linear multipole traps have been shown to be very sensitive to mis-positioning of their electrodes, which results in a symmetry breaking and leads to extra local mi…
