Ion trapping and clearing

, 1992
Ion trapping in the electron beams of future factories is one of the major issues to be addressed. After a brief review of the adverse effects of neutralization in particle storage rings, the basic topics of ion production by ionization of the residual gas are recalled: ion production rate, natural clearing rates, ion kinematics, and conditions of ...

Interfacial Ion‐Trapping Electrolyte‐Gated Transistors for High‐Fidelity Neuromorphic Computing

Advanced Functional Materials, 2022
Li+ electrolyte‐gated transistors (EGTs) have received much attention as artificial synapses for neuromorphic computing. EGTs, however, have been still challenging to achieve long‐term synaptic plasticity, which should be linearly and symmetrically ...

Quantum chaos of an ion trapped in a linear ion trap

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2000
We describe the transition to quantum chaos of an ion trapped in a linear ion trap and interacting with two laser fields. Under the conditions of adiabatic illumination of the upper level of the ion, and when the frequencies of the two laser beams are slightly different, the system is reduced to a quantum linear oscillator interacting with a ...

Efficient and irreversible capture of strontium ions from aqueous solution using metal-organic frameworks with ion trapping groups.

Dalton Transactions, 2019
Efficient and irreversible capture of radioactive nuclides is an important environmental protection task when disposing of nuclear wastewater. This paper uses an "ion trapping" concept to design an efficient adsorbent based on a metal-organic framework ...

Quadrupole ion traps

Mass Spectrometry Reviews, 2009
AbstractThe extraordinary story of the three‐dimensional radiofrequency quadrupole ion trap, accompanied by a seemingly unintelligible theoretical treatment, is told in some detail because of the quite considerable degree of commercial success that quadrupole technology has achieved.

Cryogenic Ion Trap for Minimization of Trapped Ion Loss

Japanese Journal of Applied Physics, 2001
A cryogenic linear ion trap was developed for the minimization of the loss of trapped Be+ ions. Buffer gas cooling as well as laser cooling for light element ions was tested in the cryogenic trap. The lifetime for the He-gas-cooled Be+ ions was longer than 15 min with a liquid-He-cooled trap, although they are known to be difficult to cool with a ...
