Production of highly charged ions of rare species by laser-induced desorption inside an electron beam ion trap
Christoph Schweiger, Charlotte König, José R. Crespo López-Urrutia +13
This paper reports on the development and testing of a novel, highly efficient technique for the injection of very rare species into electron beam ion traps (EBITs) for the product…
High Resolution Photoexcitation Measurements Exacerbate the Long-Standing Fe XVII Oscillator Strength Problem
Steffen Kühn, Chintan Shah, José R. Crespo López-Urrutia +29
For more than 40 years, most astrophysical observations and laboratory studies of two key soft x-ray diagnostic transitions, and , in Fe XVII ions found oscillator…
Detection of the orbital crossing and its optical clock transition in Pr
H. Bekker, A. Borschevsky, Z. Harman +5
Recent theoretical works have proposed atomic clocks based on narrow optical transitions in highly charged ions. The most interesting candidates for searches of new physics are tho…
Unlocking the Capabilities of Future High-Resolution X-ray Spectroscopy Missions Through Laboratory Astrophysics
Gabriele Betancourt-Martinez, Hiroki Akamatsu, Didier Barret +46
Thanks to high-resolution and non-dispersive spectrometers onboard future X-ray missions such as XRISM and Athena, we are finally poised to answer important questions about the for…
Revisiting the Fe XVII line emission problem: laboratory measurements of the 3s-2p and 3d-2p line-formation channels
Chintan Shah, José R. Crespo López-Urrutia, Ming Feng Gu +5
We determined relative X-ray photon emission cross sections in Fe XVII ions that were mono-energetically excited in an electron beam ion trap. Line formation for the 3s (3s-2p) and…
Closed-cycle, low-vibration 4 K cryostat for ion traps and other applications
P. Micke, J. Stark, S. A. King +7
In-vacuo cryogenic environments are ideal for applications requiring both low temperatures and extremely low particle densities. This enables reaching long storage and coherence ti…
A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions
Tobias Leopold, Steven A. King, Peter Micke +5
A cryogenic radio-frequency ion trap system designed for quantum logic spectroscopy of highly charged ions is presented. It includes a segmented linear Paul trap, an in-vacuum imag…
