Isotope-selective Ion trapping via sympathetic cooling using a surface-electrode trap with a hole for collimated atomic loading [PDF]
Scientific ReportsWe developed a surface-electrode ion trap with a square hole measuring $$40\,\mathrm {\mu m}$$ for atomic loading. The hole was fabricated using anisotropic etching of a silicon substrate and was designed to minimize potential distortion in the trapping ...

Simulations of ion trapping in a micrometer-sized cylindrical ion trap [PDF]
Journal of the American Society for Mass Spectrometry, 2006 We have performed detailed SIMION simulations of ion behavior in micrometer-sized cylindrical ion traps (r0 = 1 microm). Simulations examined the effects of ion and neutral temperature, the pressure and nature of cooling gas, ion mass, trap voltage and frequency, space-charge, fabrication defects, and other parameters on the ability of micrometer-sized

Differences in how NMDA antagonists modulate negative affective biases in male rats may serve as a predictor of clinical efficacy in major depressive disorder [PDF]
Translational PsychiatryAffective biases shape cognitive and emotional behaviour and are important in major depressive disorder (MDD). Modulation of affective biases by the NMDA antagonist, ketamine, may underlie its antidepressant effects but not all NMDA antagonists are ...

High-Stability Cryogenic System for Quantum Computing With Compact Packaged Ion Traps
IEEE Transactions on Quantum Engineering, 2022 Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultrahigh vacuum (UHV) environment for maintaining long ion chains for extended periods of time.

Analysis of Multipolar Linear Paul Traps for Ion–Atom Ultracold Collision Experiments
Atoms, 2021 We evaluate the performance of multipole, linear Paul traps for the purpose of studying cold ion–atom collisions. A combination of numerical simulations and analysis based on the virial theorem is used to draw conclusions on the differences that result ...

Microfabricated ion traps [PDF]
Contemporary Physics, 2011 Ion traps offer the opportunity to study fundamental quantum systems with high level of accuracy highly decoupled from the environment. Individual atomic ions can be controlled and manipulated with electric fields, cooled to the ground state of motion with laser cooling and coherently manipulated using optical and microwave radiation.

Ion generation and loading of a Penning trap using pulsed laser ablation
New Journal of Physics, 2020 We investigated the production of aluminum and beryllium ions via pulsed laser ablation using 355 nm wavelength and 5 ns long laser pulses. The ablation threshold of Al ^+ and Be ^+ was measured to be 0.9 ± 0.1 (stat.) ± 0.3 (syst.) J cm ^−2 and 1.4 ± 0 ...
