100-fold reduction of electric-field noise in an ion trap cleaned with in situ argon-ion-beam bombardment.
Motional heating of trapped atomic ions is a major obstacle to their use as quantum bits in a scalable quantum computer. The detailed physical origin of this heating is not well understood, but experimental evidence suggests that it is caused by electric-field noise emanating from the surface of the trap electrodes. In this study, we have investigated the role of adsorbates on the electrodes by...
متن کاملEnergy Transfer in Solid Argon during Ion Bombardment
Solid argon is a model system for studies of radiative and nonradiative processes associated with electronic excitation by MeV light ion bombardment. The electronic excited states, excitons and excimers, have been extensively studied in this material and careful studies have also been made of the ejection (sputtering) of atoms from the surface. The sputtering requires transfer of energy from el...
متن کاملIon beam formation in a low-pressure geometrically expanding argon plasma
Supersonic ion beam formation has been observed in a geometrically expanding low-pressure inductively coupled argon plasma. It is found that the ion beam is only observed below 3 mTorr and only when the discharge is operated in inductive mode. The geometrical expansion of the plasma induces density and potential gradients leading to the ion beam formation. The ion beam energy increases with dec...
