Gabrielse Research Programs

  1. Most Precise Measurements of the Electron's Magnetic Moment
    and the Fine Stucture Constant

    The one-electron quantum cyclotron developed during a 20 year research program resulted in a measurement of the electron's magnetic moment,
    Measured g value,
    that is 15 times more precise than the value that had been accepted for 20 years. The new devices and methods employed to realize the one-particle quantum cyclotron include a one-particle self-excited oscillator, inhibition of spontaneous emission, a self-shielding superconducting solenoid, and a cylindrical Penning trap.

  2. The positron magnetic moment is to be measured next - to provide the most stringent test of CPT invariance with leptons.
  3. 680-fold improved measurement of the antiproton magnetic moment

    The antiproton magnetic moment (scaling naturally as a nuclear magneton rather than a Bohr magneton) is much more difficult to detect than is that of an electron. A research program underway seeks to improve the precision with which the antiproton and proton can be compared by a factor of a million or more, to make a stringent test of CPT invariance with baryons. After realizing the first one-proton self-excited oscillator and using it to measure the proton magnetic moment at the level of a few ppm , the apparatus has been installed at the Antiproton Deccelerator at CERN. This year it was used to make a measurement that is 680 more precise than previous measurements . The next goal is to use quantum jump spectroscopy and a two-trap method to reach ppb precision.

  4. Comparing the Antiproton and Proton: Most Stringent Test of CPT invariance with Baryons

    Prof. Gabrielse initiated low energy antiproton physics when he, and the small TRAP team that he led, first slowed antiprotons in matter, captured them in a trap, cooled them via electron-cooling in a trap, and accumulated them for low energy measurements. Their comparison of the charge-to-mass ratios of the antiproton and proton,
    Measured antiproton to proton charge to mass
                    ratio,
    9 parts in 1011
    has stood for many years as the most stringent test of CPT invariance with baryons.
  5. Cold Antihydrogen Studies

    Gabrielse initiated cold antihydrogen physics, by providing the methods used to make cold antiprotons available for experiments (above) and by outlining how cold antihydrogen atoms could be produced from trapped antiprotons. The nested Penning trap that Gabrielse and his students demonstrated is a device and method that he and collaborators invented to make opposite sign particles interact long enough for atom formation. Gabrielse and his ATRAP team were one of two teams that first observed the antihydrogen atoms made using this device and method. ATRAP's field ionization detection technique allowed a background-free observation and the only measurement method so for that determines the states of antihydrogen that are being produced. Their method to drive the production of antihydrogen substantially increased the production rate. ATRAP later demonstrated a second method to produce slow antihydrogen, for the first time using lasers to control the production via a charge exchange method.

    Shortly after first trapping antiprotons, Gabrielse proposed that the cold antihydrogen atoms be confined in a magnetic trap for precise laser spectroscopy – to compare antihydrogen and hydrogen atoms. This vision and approach is now being pursued by four international collaborations, working at a storage ring that CERN built to allow the pursuit of this vision, and using the his cold antiproton methods. His ATRAP team observed the first production of antihydrogen atoms within the fields of a Ioffe trap. The ALPHA team reports that an antihydrogen atom is so trapped in one of ten trials. ASACUSA is pursuing the production of antihydrogen atoms in a CUSP trap. AEGIS proposes to do antihydrogen gravity experiments, using his cold antiproton methods and the dilution refrigerator methods to produce cold positrons that he and his students demonstrated with electrons. ATRAP's recent focus has been to produce colder antiproton plasmas at much lower temperatures as a step to producing usable numbers of antihdyrogen atoms that are cold enough to be trapped.

  6. Searching for the Electron Electric Dipole Moment

    Prof. Gabrielse and his collaborators seek to measure the electron's electric dipole moment using cold ThO molecules. The experiment is under development.
