(a novel parabolic mirror ion trap; We measured the trap to have a light collection efficiency of 39%, nearly an order of magnitude higher than the light collection of ion traps utilizing standard collection optics) Wikipedia, Oct. 24, 2022: Ion trap (An ion trap is a combination of electric or magnetic fields used to capture charged particles--known as ions--often in a system isolated from an external environment. Ion traps have a number of scientific uses such as mass spectrometry, basic physics research, and controlling quantum states. The two most common types of ion trap are the Penning trap, which forms a potential via a combination of electric and magnetic fields, and the Paul trap which forms a potential via a combination of static and oscillating electric fields) Ion trap - an overview, via ScienceDirect, Oct. 24, 2022 (Ion traps, also referred to as quadrupole ion traps, trap and store ions in an orbital motion within the ion trap and eject ions for detection; Ion trap mass analyzers use a combination of electric or magnetic fields to capture or "trap" ions inside the mass analyzer. There are multiple configurations of ion traps including 3D ion traps (the Paul ion trap), a linear ion trap (2D trap), and electrostatic trap (Orbitrap), or a magnetic field-based trap (ion cyclotron resonance); Ion trap structures are usually installed in a high-vacuum enclosure to minimize collisions with background gas. Ions are often loaded by transmitting a beam of neutral atoms of the desired element and an ionizing electron beam through the trap simultaneously. When the atoms are ionized inside the trapping zone, the resulting ions can be trapped) Dictionary.com, Oct. 24, 2022 (ion trap: noun, Physics. any device used to prevent ions in an electron beam from striking other apparatus, especially in mass spectrometry.) Collins English dictionary online, Oct. 24, 2022 (ion trap: a combination of electric or magnetic fields used to capture charged particles) Quantiki website, Oct. 24, 2022 (Ion traps. Ions, or charged atomic particles, can be confined and suspended in free space using electromagnetic fields. Qubits are stored in stable electronic states of each ion, and quantum information can be processed and transferred through the collective quantized motion of the ions in the trap (interacting through the Coulomb force); Ion traps were first invented in the 1960's by Wolfgang Paul and Hans Dehmelt (who received the Nobel Prize in 1989 for their work). The idea is that since a charged particle can not be confined in three dimensional space using static electric fields, an electric field oscillating at radio frequency (RF) is applied instead, forming a potential with the shape of a saddle spinning at the RF frequency. The ions, interacting with this oscillating potential over time, end up trapped in the middle of the saddle potential) |
