The text below was written during two visits that Daniel Segal made at Universit{\'e} Paris 13. Danny stayed at Laboratoire de Physique des Lasers the summers of 2008 and 2009 to participate in the exploration of a novel lead in the field of ultra-hi

Laser-cooled atomic ions form ordered structures in radiofrequency ion traps and in Penning traps. Here we demonstrate in a Penning trap the creation and manipulation of a wide variety of ion Coulomb crystals formed from small numbers of ions. The co

We present a thorough analysis of the electronic detection of charged particles, confined in a Penning trap, via image charges induced in the trap electrodes. Trapping of charged particles in an electrode structure leads to frequency shifts, which ar

We report a study of the axialization and laser cooling of single ions and small clouds of ions in a Penning trap. A weak radiofrequency (rf) signal applied to a segmented ring electrode couples the magnetron motion to the cyclotron motion, which res

The quantum jump statistics for the three stable isotopes of Mg+ have been studied experimentally. Single ions of magnesium were held and laser cooled in a Penning trap. Quantum jumps were observed by collecting the resonance fluorescence near 280 nm

We have trapped and sympathetically cooled the molecular ions HCO and N2H 1 in a Penning trap. Through their Coulomb interaction with laser-cooled Mg ions the molecules were sympathetically cooled to cryogenic temperatures. We identify the molecules

We have studied the motional dynamics of ions stored in an ion trap of novel geometry, a linear combined trap, which combines the trapping fields of a linear rf trap and a Penning trap. The motional frequencies of trapped Mg+ ions are measured as a f
