“…A multicell trap (MCT) system similar to that proposed some years ago is envisioned [18,19]. An existing 5 T solenoidal magnet, previously used for studies of atomic clusters [20][21][22], will be used to provide the confining magnetic field for PAX. A schematic diagram of the setup is shown in figure 2.…”

Electron-positron plasmas are unique in their behavior due to the mass symmetry. Strongly magnetized electron-positron, or pair, plasmas are present in a number of astrophysical settings, such as astrophysical jets, but they have not yet been created in the laboratory. Plans for the creation and diagnosis of pair plasmas in a stellarator are presented, based on extrapolation of the results from the Columbia Non-neutral Torus stellarator, as well as recent developments in positron sources. The particular challenges of positronium injection and pair plasma diagnostics are addressed.

Abstract. The former Berlin electron-beam ion trap (EBIT) has been moved to Greifswald. In addition to X-ray studies the setup will be used for the investigation of interaction processes between highly-charged ions and atomic clusters such as charge exchange and fragmentation. The EBIT setup has been reassembled and highlycharged ions have been produced from Xe-Ar gas mixtures to study the "sawtooth effect". In addition, the layout of the extraction beamline, interaction region and product analysis for the interaction studies with highly-charged ions are presented.

“…The experiments have been performed at the ClusterTrap, a setup designed for production and investigation of gas-phase cluster ions [17,[24][25][26]. For the present studies, metal clusters have been produced by laser irradiation of a metal wire and subsequent expansion of the vapor into vacuum by means of a helium gas pulse [27].…”

“…After ejection from this trap, they are guided by an electrostatic quadrupole deflector and other ion-optical elements into a 12-T cylindrical Penning trap (inset in Fig. 1) [17,24]. During in-flight capture and storage, cluster ions are mass-overcharge selected and exposed to interaction steps of interest.…”

Electron attachment to anionic clusters in ion traps

Ion traps are versatile tools for the investigation of gas-phase cluster ions, allowing, e.g., cluster-size selection and extended reaction times. Taking advantage of their particular storage capability of simultaneous trapping of electrons and clusters, Penning traps have been applied for the production of clusters with high negative charge states. Recently, linear radio-frequency quadrupole traps have been demonstrated to be another candidate to produce polyanionic clusters. Operation with rectangular, rather than harmonic, radio-frequency voltages provides field-free time slots for unhindered electron passage through the trap. Several aspects of electron-attachment techniques by means of Penning and radio-frequency traps are addressed and recent experimental results are presented.
