WebThe two main types of ion trap (the Paul, or radiofrequency, trap and the Penning trap) were both introduced at about the same time. Wolfgang Paul and his group in Bonn developed … WebThe high performance is due to the fact that ions are detected by their cyclotron resonance frequencies, which can be measured extremely accurately. The ICR analyzer is a type of ion trap (a Penning trap) consisting of a cell under high vacuum (10 −10 Torr) located inside a superconducting magnet (3–14.5 T). The stability of the magnetic ...
WebPenning-trap mass spectrometry in atomic and nuclear physics has become a well-established and reliable tool for the determination of atomic masses. In combination with … WebA commercial, position-sensitive ion detector was used for the first time for the time-of-flight ion-cyclotron resonance detection technique in Penning trap mass spectrometry. In this work, the characteristics of the d…
WebThe ion trap functions as a mass spectrometer when the trapping field is changed, so that the trajectories of simultaneously trapped ions of consecutive specific mass/charge ratio become sequentially unstable, and ions leave the trapping field in … Webgroup to trap a single ion in the Penning trap failed due to an unexpectedly low fluorescence count rate per ion. This led us to simulate the cooling dynamics to investigate the possibility that “trapped states” might be the cause. Although there were trapped states in our scheme we were able to show that it was
WebOnly a single ion, or linear strings of ions, can be cooled to the quantum ground state across all the motional modes in an RF trap; away from the RF null ions are susceptible to RF heating. Penning traps do not suffer from this limitation, and more interesting two and three dimensional structures could, potentially, be cooled to the ground state. ot show costWeb11. apr 2024 · Ion-driven destabilization of a toroidal electron plasma in a small aspect ratio axisymmetric toroidal device is reported for A r + ions of different initial density values using a high fidelity 3D3V PIC solver.
