Artificially Structured Boundary for a high purity ion trap or ion source

First ion pulses out of a laser ion source trap

Resonance ionization laser ion sources (RILIS) are applied for the production of exotic ion beams with high isotopic and isobaric purity [1], limited only by surface ionization of unwanted atomic species. A new type of resonance ionization laser ion source is presently being deve-loped and tested at the RISIKO mass separator at Mainz University [2] for future use at on-line radioactive ion beam...

Tests of a Laser Ion Source at the Heidelberg Electron Beam Ion Trap

A laser ion source (LIS) has been designed and successfully tested for loading the Heidelberg electron beam ion trap (H-EBIT) with ions of practically all solid-state elements. A pulsed YAG:Nd laser (30 mJ, 8 ns) is used to produce plasma from a solid target. Lowly charged ions are extracted from the plasma and accelerated by a short high-voltage pulse, generating a pulsed ion beam with energy ...

Lett . 1 Inter - ion Coulomb interactions in a Magneto - Optical Trap Ion Source

We have investigated the role played by inter-ion Coulomb interactions in a magneto-optical trap ion source (MOTIS). Using a Monte Carlo simulation accounting for all pair-wise ion-ion Coulomb interactions in the source, we have calculated the broadening of the transverse spatial and velocity distributions as well as the increase in emittance over a range of beam currents and extraction electri...

Ion-Trap Quantum Computation

Quantum computation requires a very special physical environment. Numerous operations must be performed on the quantum states of the qubits (or quantum bits) before those states decohere, or lose the interlocking phase relationships that give quantum computation its power. Thought to be an unavoidable outcome of the interaction between the quantum state and the environment, decoherence threaten...
