“…[] It is a variation of a closed cylindrical Penning trap, with one closed endcap replaced by open cylindrical electrodes to allow injection and ejection of particles, and the other endcap being electrically closed while optically transparent, which in the present case is realized by a window with a conductive coating of indium tin oxide (ITO) . This special electrode arrangement has the confinement region in close proximity to the optically open endcap, and thus features a largely enhanced solid angle of detection as compared to the standard open‐endcap design . Tests have shown that highly charged ions can be confined for periods of days in this trap under well‐defined conditions.…”

“…In highly charged ions, such electron magnetic moment measurements are possible in two complementary ways, either by the continuous Stern–Gerlach effect applied to ions with zero‐spin nuclei, in full similarity to the measurements, or by making use of the fact that in highly charged ions above a certain value of Z , the hyperfine structure of a few‐electron ion becomes accessible for laser spectroscopy . Here, we discuss this latter approach by the ARTEMIS experiment with highly charged ions in a cryogenic Penning trap that is optimized for optical spectroscopy under large solid angles . This experiment is located at the HITRAP facility at GSI, Germany.…”

The magnetic moment (g-factor) of the electron is a fundamental quantity in physics that can be measured with high accuracy by spectroscopy in Penning traps. Its value has been predicted by theory, both for the case of the free (unbound) electron and for the electron bound in a highly charged ion. Precision measurements of the electron magnetic moment yield a stringent test of these predictions and can in turn be used for a determination of fundamental constants such as the fine structure constant or the atomic mass of the electron. For the bound-electron magnetic-moment measurement, two complementary approaches exist, one via the so-called "continuous Stern-Gerlach effect", applied to ions with zero-spin nuclei, and one a spectroscopic approach, applied to ions with nonzero nuclear spin. Here, the latter approach is detailed, and an overview of the experiment and its status is given.

“…ITO remains conductive and optically transparent at cryogenic temperatures. [89] Second, an additional pair of linear dummy traps is added at either side of the array. The 10 central linear traps used for the quantum register are thereby increased to 14 linear traps.…”

An ion‐lattice quantum processor based on a two‐dimensional arrangement of linear surface traps is presented. The design features a tunable coupling between ions in adjacent lattice sites and a configurable ion‐lattice connectivity, allowing one, for example, to realize rectangular and triangular lattices with the same trap chip. Detailed trap simulations of a simplest‐instance ion array with 2 × 9 trapping sites are presented and the fabrication of a prototype device in an industrial facility is reported on. The design and the employed fabrication processes are scalable to larger array sizes. Trapping of ions in rectangular and triangular lattices and transport of a 2 × 2 ion‐lattice over one lattice period are demonstrated.

“…By employing of a non-neutral plasma method, a linear trapping model that accounts for large ion clouds has been demonstrated which will become the core of an atomic clock [273]. A novel cryogenic Penning trap geometry, intended to perform high resolution spectroscopy and experiments and enhanced resolution imaging of levitated particles is described in [274].…”

Charged (nano)particles confined in electrodynamic traps can evolve into strongly correlated Coulomb systems, which are the subject of current investigation. Exciting physical phenomena associated to Coulomb systems have been reported such as autowave generation, phase transitions, system self-locking at the ends of the linear Paul trap, self-organization in layers, or pattern formation and scaling. The dynamics of ordered structures consisting of highly nonideal similarly charged nanoparticles, with coupling parameter of the order Γ = 10 8 is investigated. This approach enables us to study the interaction of nanoparticle structures in presence and in absence of the neutralizing plasma background, as well as to investigate various types of phenomena and physical forces these structures experience. Applications of electrodynamic levitation for mass spectrometry, including containment and study of single aerosols and nanoparticles are reviewed, with an emphasis on state of the art experiments and techniques, as well as future trends. Late experimental data suggest that inelastic scattering can be successfully applied to the detection of biological particles such as pollen, bacteria, aerosols, traces of explosives or synthetic polymers.
