Cyclotron-Frequency Stability via Single-Ion Fluorescence in a Penning Trap with a Cryogen-Free Superconducting Magnet
Anna Schupeta, David Yousaf, Manuel Almagro +6
In this work, we investigate the magnetic-field stability of a Penning trap operated with a cryogen-free superconducting magnet through cyclotron-frequency measurements of a single…
Enhancing non-destructive mass identification via Fourier-transform fluorescence analysis
Francisco Domínguez, David Yousaf, Joaquín Berrocal +4
Single-ion mass identification is important for atomic and nuclear physics experiments on ions produced with low yields. Cooling the ion to ultra-low temperatures by interacting wi…
High-performance in-vacuum optical system for quantum optics experiments in a Penning-trap
Joaquín Berrocal, Daniel Rodríguez
Accurate measurements with implications in many branches in Physics have been accessed using Penning traps and conventional techniques within a temperature regime where each eigenm…
Penning-trap eigenfrequency measurements with optical radiofrequency detectors
Joaquín Berrocal, Alejandro Hernández, Íñigo Arrazola +5
We use an electric-dipole laser-driven transition to precisely measure the cyclotron-frequency ratios of the pairs Ca-Ca, Ca-Ca and $^{4…
A Coupled-Oscillators Model to Analyze the Interaction between a Quartz Resonator and Trapped Ions
Emilio Altozano, Joaquín Berrocal, Steffen Lohse +4
The novel application of a piezoelectric quartz resonator for the detection of trapped ions has developed in the observation of the quartz-ions interaction under non-equilibrium co…
Formation of Two-Ion Crystals by Injection from a Paul-Trap Source into a High-Magnetic-Field Penning Trap
Joaquín Berrocal, Emilio Altozano, Francisco Domínguez +6
Two-ion crystals constitute a platform for investigations of quantum nature that can be extended to any ion species or charged particle provided one of the ions in the crystal can…
Non-equilibrium Coupling of a Quartz Resonator to Ions for Penning-Trap Fast Resonant Detection
Joaquín Berrocal, Steffen Lohse, Francisco Domínguez +5
The coherent coupling between a quartz electro-mechanical resonator at room temperature and trapped ions in a 7-tesla Penning trap has been demonstrated for the first time. The sig…
Dynamics of an unbalanced two-ion crystal in a Penning trap for application in optical mass spectrometry
Manuel J. Gutiérrez, Joaquín Berrocal, Francisco Domínguez +4
In this article, the dynamics of an unbalanced two-ion crystal comprising the 'target' and the 'sensor' ions confined in a Penning trap has been studied. First, the low amplitude r…
The TRAPSENSOR Facility: an Open-Ring 7-Tesla Penning Trap for Laser-Based Precision Experiments
Manuel J. Gutiérrez, Joaquín Berrocal, Juan Manuel Cornejo +12
The Penning-trap electronic-detection technique that offers the precision and sensitivity requested in mass spectrometry for fundamental studies in nuclear and particle physics has…
Motional studies of one and two laser-cooled trapped ions for electric-field sensing applications
Francisco Domínguez, Manuel Jesús Gutiérrez, Íñigo Arrazola +7
We have studied the dynamics of one and two laser-cooled trapped Ca ions by applying electric fields of different nature along the axial direction of the trap, namely, d…
