Towards Frequency Metrology of the Optical Hyperfine Structure of Highly Charged Ions Using Quantum Logic

Peter Micke
BASE Collaboration, CERN, Geneva

Highly charged ions (HCI) are extreme atoms with favorable properties for the study of fundamental physics and the search for new physics [1]. They feature a simple atomic structure due to a small number of bound electrons, strong electromagnetic fields to which the electrons are exposed, and a low sensitivity to external perturbing fields [2]. Recent developments such as Coulomb crystallization [3], the application of quantum logic [4], and algorithmic ground-state cooling [5] have made HCI accessible for use in the most accurate measurement devices: optical atomic clocks, which today reach fractional uncertainties of 10-18.

In this talk, I will briefly review how we overcame all previous obstacles to realize the first optical atomic clock based on an HCI. I will present our frequency ratio measurement of the ground-state fine-structure transition in Ar13+ at 441 nm against the electric-octupole transition in 171Yb+ at a fractional uncertainty of about 1x10-16, limited by statistics and improving the previous uncertainty level by eight orders of magnitude [6]. By comparing the transition frequencies of the two isotopes 40Ar13+ and 36Ar13+, we determined the isotope shift with a relative uncertainty of 5.7x10-11, an improvement of nine orders of magnitude that resolves the QED nuclear recoil contribution [6]. In the second part of my talk, I will discuss how the measurement concept can be extended to optical hyperfine-structure transitions which are available in heavy hydrogen-like or lithium-like HCI.

ExHILP 2021

The forth Extremely High Intensity Laser Physics Conference (ExHILP 2021) – held as an online conference – is hosted by the Friedrich Schiller University of Jena and the Helmholtz Institut Jena and co-organized by the DFG research unit FOR 2783. The conference combines theory, experiment and simulations of laser-matter and laser-vacuum interactions at the highest intensities. This year’s version of  ExHILP is focusing on several core topics of Strong Field Quantum Electrodynamics and its application in neighboring fields. A focus will be on contemporary and future experiments with PW-class lasers addressing interactions in plasmas, the nonlinear response of the quantum vacuum, and laser interactions with ultra-relativistic particle and high energy photon beams.

Registration is open now on the conference website.

This thesis describes the development of a particle counter based on a Cerium activated yttrium aluminium perovskite (YAP:Ce) scintillator. The detector is designed for charge exchange experiments at the relocated ion storage ring CRYRING at the GSI Helmholtz Zentrum für Schwerionenforschung in Darmstadt. It will be used for charge exchange experiments. The suggested detector design was developed regarding the requirements set by the desired ultra high vacuum conditions of up to 10−12 mbar at CRYRING in combination with a high radiation hardness against ion irradiation. The design was kept as simple as possible offering an easy exchange of the scintillator (not limited to YAP:Ce) if necessary.

For an estimation of the detector lifetime the radiation hardness was systematically investigated for Hydrogen, Oxygen and Iodine irradiation in the energy regime of 1 – 10 MeV. The measurement took place at the JULIA tandem accelerator. For the measurement of detector degradation the light yield was used. Values determined for the critical fluence, defined as fluence at half the initial light yield, varied from 1 × 1015 cm−2 in the case of hydrogen down to 1.7 × 1012 cm−2 for iodine irradiation.

Prior to the hardness investigation, the used photomultiplier tube (PMT) was tested for anomalous behaviour like temporal or spatial dependence of the output signal. Taking the experimental uncertainties into account no such dependencies could be observed. It was concluded that the investigated PMT was well suited for the use in the experiment and later on the particle counter.

5th International FAIR School

The fifth edition of the International FAIR School will take place in Castiglione della Pescaia, Italy from September 03-10, 2017. The conference venue is the Riva del Sole

The scientific program of the International FAIR School covers all aspects of the FAIR project. The accelerators, the experiments, the theories and the computing frameworks behind. Devoting a day each on the four scientific pillars of FAIR (APPA, CBM, NUSTAR and PANDA) and two additional days for the accelerator itself and the High Performance Computing facilities gives the participants plenty of time to learn about the FAIR project. Furthermore the school is a great example of the multidisciplinary spirit of FAIR. In a series of expert lectures and group projects the different scientific parts will be elaborated. There will be plenty of time to get to know other international students working on FAIR related projects. The lectures are aimed at early PhD students/advanced master students.

Institute´s Seminar

This tutorial-talk presents an introduction to the interaction of light and matter on the attosecond timescale. My aim is to overview the theoretical description of ultra-short time-delays, and to relate these to the phase of extreme ultraviolet (XUV) light pulses and to the asymptotic phase-shifts of photoelectron wave packets. Special emphasis is laid on time-delay experiments, where attosecond XUV pulses are used to photoionize target atoms at well-defined times, followed by a probing process in real time by a phase-locked, infrared laser field. In this way, the laser field serves as a "clock" to monitor the ionization event, but the observable delays do not correspond directly to the delay associated with single-photon ionization. Instead, a significant part of the observed delay originates from a measurement induced process, which obscures the single-photon ionization dynamics. This phase-lag effect is traced back to a phase-shift of the above-threshold ionization transition matrix element, which we call the continuum--continuum phase.

It arises due to the laser-stimulated transitions between Coulomb continuum states. As we shall show here, these measurement-induced effects can be separated from the single-photon ionization process, using analytical expressions of universal character, so that eventually the attosecond time-delays in photoionization can be accessed. Finally, I will show results of atomic delay calculations performed using diagrammatic many-body perturbation theory.

RS-APS Seminar

Owing to the recent advances in heavy-ion accelerator facilities and in detection techniques, new possibilities arise to study the electronic structure of simple atomic systems in strong Coulomb fields. Relativistic, quantum electrodynamics, and even nuclear effects, which are difficult to isolate in neutral atoms, often become enhanced in high-Z, few-electron ions. In order to improve understanding of these fundamental interactions, a number of studies have been recently carried out on the characteristic photon emission from heavy ions. In this contribution, we present a theoretical study on angular properties of radiation decay of heavy atomic systems. Special attention is given to the question of how the hyperfine interaction of the nuclear magnetic moment with those of electrons affects the angular properties of the K-alpha emission for isotopes with non-zero nuclear spin. A quite sizable contribution of the hyperfine interaction upon the K-alpha angular emission is found for isotopes with nuclear spin I = ½. Furthermore, lifetime-induced effects on angular distribution and correlation of x-ray emissions from two-step radiative cascades with more than one intermediate resonance are also investigated respectively. It is found that the angular properties of emitted x-ray photons are very sensitive to small energy splitting of the intermediate resonances, which can be used to determine small energy differences.

12th International Symposium on Electron Beam Ion Sources and Traps (EBIST´14)

The 12th International Symposium on Electron Beam Ion Sources and Traps, EBIST'14 will be held on May 18 - 21, 2014 at the National Superconducting Cyclotron Laboratory (NSCL) on the campus of Michigan State University (MSU) in the mid-western "Spartan" city of East Lansing, Michigan, USA.

NSCL is a rare-isotope accelerator facility conducting advanced research in fundamental nuclear science, nuclear astrophysics, accelerator physics, and related instrumentation technologies. The facility was recently selected by the Department of Energy (DOE) to establish the US national user Facility for Rare Isotope Beams (FRIB) for basic research with rare-isotope beams.

The EBIST symposia date back to 1977 and have taken place every 3 to 4 years to specifically discuss progress and exchange ideas in the design, development, applications of electron beam ion sources and traps, and the physics with highly charged ions. The topics to be covered in 2014 are:

  • Progress and status of EBIS/T facilities,
  • Atomic spectroscopy of highly charged ions,
  • Charge-exchange and surface interaction with highly charged ions,
  • Charge breeding of stable and radioactive isotopes,
  • Nuclear physics with highly charged ions.

As in the past, the program of EBIST'14 will feature reviews and reports in a single session. We intend to organize a series of invited talks highlighting recent achievements and the future prospects in the above fields. In addition, contributions covering recent results will be selected for oral presentations. Furthermore, a small poster session is planned.

Topical Workshop of the FLAIR Collaboration

The workshop is jointly organized by the Max-Planck-Institut für Kernphysik MPIK Heidelberg, the GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, the Johannes Gutenberg-Universität, Mainz, and the Stefan-Meyer-Institut für Subatomare Physik, Vienna.

The Facility for Low-Energy Antiproton and Ion Research (FLAIR) Collaboration has been formed within the new international Facility for Antiproton and Ion Research (FAIR) at GSI, Darmstadt, Germany, and makes use of the beams of antiprotons and highly-charged ions from NESR to further decelerate and cool them in two storage rings (LSR and USR) and a universal trap facility HITRAP. Antiprotons will be provided in both slow and fast extraction with energies down to the keV-range. The anticipated beam intensities will be significantly larger than currently available reaching unprecedented phase space densities that enable many new experiments. The facility will be also used with highly charged ions, leading to a strong overlap with the SPARC collaboration.

The workshop program will concentrate on the following topics:

  • Experiments with antiprotons and antihydrogen
  • Highly charged ions in traps and rings for spectroscopy
  • Interactions of low-energy highly charged ions and antiprotons with composite and solid targets
  • Nuclear and particle physics with antiprotons
  • Heavy-ion experiments, ion surface interactions, collision dynamics
  • X-ray spectroscopy of antiprotonic atoms
  • New instrumentation and facilities

In order to allow the attendance of all sessions, no parallel sessions will be held.

"Ultrafast coherent control of electron dynamics"
Matthias Wollenhaupt
Carl von Ossietzky Universität Oldenburg, Carl-von-Ossietzky-Straße 9-11,26129 Oldenburg, Germany

The ability to generate ultrashort laser pulses of controllable shape with sub-attosecond precision has made it possible to precisely manipulate the electron dynamics of quantum systems.

Recently, we have developed a tomographic reconstruction method to directly measure three-dimensional photoelectron angular distributions resulting from REMPI in a Velocity Map Imaging (VMI) set-up. On atoms we have demonstrated the creation of designer electron wave packets using polarization shaped laser pulses [1].

In another experiment, we show how precision pulse shaping is used to manipulate the coupled electron and nuclear dynamics in order to address different bound electronic target states in a molecule. In our two-color energy resolved photoelectron spectroscopy experiment an intense IR-pulse, the phase of which is tailored to the electronic wave packet oscillation, guides the system towards a preselected target channel [2].

Finally, a femtosecond laser based approach to chiral recognition of randomly oriented molecules in the gas phase enabling implementations in analytics is presented. PAD resulting from REMPI of camphor and fenchone molecules are studied in order to investigate the Circular Dichroism in the photo-ionization of chiral molecules.  The observed circular dichroism effect using left- and right-handed circularly polarized femtosecond laser pulses is in the ± ten percent regime [3]

EMMI Workshop on "High energy density plasma diagnostics at FAIR: Novel laser based photon and particle sources"

The workshop focuses on the development of novel diagnostic methods and tools for investigations of High Energy Density Matter (HEDM).

At the Facility for Antiproton and Ion Research (FAIR), the HEDM-states will be created by intense heavy ion beams, which are capable to heat large-volume targets of any elements uniformly and quasi-isochorically. After this, an isentropic expansion in 1D planar geometry will give an opportunity for investigations of the Equation-of-state in unexplored regions of phase transitions, transport and radiation properties of HEDM.

In other experiments relevant to planetary science, multi-shock compression of e.g. cryogenic Hydrogen, inserted in a thick high Z tamper, heated by a rotating Uranium beam, will be investigated. In order to observe different phases of shock dynamics using imaging techniques, pulsed high energy radiation, particle sources an appropriate diagnostic methods are required. In this context imaging applications of laser generated beams of protons, electrons, neutrons and gamma-rays will be discussed.

Key Topics

  1. Proton generation by interaction of relativistic laser pulses with matter
  2. Electron acceleration in relativistic laser-plasmas
  3. A bright neutron source driven by short pulse lasers and applications
  4. Advanced x-ray and γ-ray sources and applications
  5. Nuclear physics in laser-matter interactions
  6. High energy flux x-ray and γ-ray detectors and optics
