Highly charged radioactive ions can be stored for extended periods of time in storage rings which allows for precision measurements of their decay modes. The straightforward motivation for performing such studies is that fully ionised nuclei or few-electron ions can be viewed as clean quantum-mechanical systems, in which the interactions of the many electrons can be either excluded or treated precisely.

Superconducting solenoid system with adjustable shielding factor for precision measurements of the properties of the antiproton

Tokyo (main)) ; Blessing, Pascal E (RIKEN (main) ; Darmstadt, GSI) ; Borchert, Matthias J (RIKEN (main) ; Leibniz U., Hannover) ; Erlewein, Stefan (RIKEN (main) ; CERN ; Heidelberg, Max Planck Inst.) ; Hansen, Jannek J (RIKEN (main)) ; Morgner, Jonathan (RIKEN (main) ; Leibniz U., Hannover) ; Bohman, Matthew A (RIKEN (main) ; Heidelberg, Max Planck Inst.) et al.
A superconducting self-shielding three-solenoid system with an adjustable shielding factor is developed, implemented, and characterized using a single antiproton in a Penning trap. With the tuned system, we suppress external magnetic field disturbances by up to a factor of 225 ± 15, allowing antiproton-to-proton charge-to-mass ratio comparisons with fourfold reduced frequency fluctuations and antiproton magnetic moment determinations with tenfold reduced uncertainty..

We describe a newly developed polytetrafluoroethylene/copper capacitor driven by a cryogenic piezoelectric slip-stick stage and demonstrate with the chosen layout cryogenic capacitance tuning of ≈60 pF at ≈10 pF background capacitance. Connected to a highly sensitive superconducting toroidal LC circuit, we demonstrate tuning of the resonant frequency between 345 and 685 kHz, at quality factors Q > 100 000. [...]
