Cold highly charged ions in a radio-frequency trap with superconducting magnetic shielding
Elwin A. Dijck, Christian Warnecke, Malte Wehrheim +12
We implement sympathetic cooling of highly charged ions (HCI) by fully enclosing a linear Paul trap within a superconducting radio-frequency resonator. A quantization magnetic fiel…
An ultralow-noise superconducting radio-frequency ion trap for frequency metrology with highly charged ions
J. Stark, C. Warnecke, S. Bogen +17
We present a novel ultrastable superconducting radio-frequency (RF) ion trap realized as a combination of an RF cavity and a linear Paul trap. Its RF quadrupole mode at 34.52 MHz r…
Lifetime measurement of the 5dD state in Ba
Amita Mohanty, Elwin A. Dijck, Mayerlin Nuñez Portela +5
The lifetime of the metastable 5dD state has been measured for a single trapped Ba ion in a Paul trap in Ultra High Vacuum (UHV) in the 10 mbar pressure ran…
Effect of soil temperature on one-way optical frequency transfer through dense-wavelength-division-multiplexing fibre links
T. J. Pinkert, O. Böll, G. S. M. Jansen +8
Results of optical frequency transfer over a carrier-grade dense-wavelength-division-multiplexing (DWDM) optical fibre network are presented. The relation between soil temperature…
First Test of Lorentz Invariance in the Weak Decay of Polarized Nuclei
S. E. Müller, E. A. Dijck, H. Bekker +17
A new test of Lorentz invariance in the weak interactions has been made by searching for variations in the decay rate of spin-polarized 20Na nuclei. This test is unique to Gamow-Te…
A new approach to test Lorentz invariance
H. W. Wilschut, E. A. Dijck, S. Hoekstra +9
Lorentz invariance in the weak interaction has been tested rather poorly compared to the electromagnetic interaction. In this work we show which tests on the weak interaction shoul…
