08.12.21: Innovative cooling technique of the BASE collaboration among the Physics World Top 10 Breakthroughs in 2021

An innovative particle cooling technique of the BASE collaboration has been selected to be among the Physics World Top 10 Breakthroughs in 2021 external Link.

In 2021, our former division member Dr. Matthew Bohman and the BASE collaboration external Link demonstrated the first sympathetic cooling of a single proton using a cryogenic two-Penning-trap system in "Natureexternal Link (see our news of 25.08.21). To this end, the single proton was stored in a proton trap and a cloud of Be+ ions in a separate beryllium trap. The coupling was realized by connecting the two Penning traps to a superconducting cryogenic LC circuit with resonance frequency near their axial frequencies. This new cooling technique allows to reach proton temperatures far below the environment temperature. In the demonstration measurement, the proton temperature was reduced by 85%, from 17 K environment temperature to 2,6 K.

The novel sympathetic laser-cooling technique will enable enhanced precision experiments of any charged species at lower temperatures. In particular, it can be readily applied to cool protons and antiprotons in the same large macroscopic traps that enable precision measurements of the charge-to-mass ratio and g-factor. This will allow for improved precision in matter-antimatter comparisons and dark matter searches, performed by the BASE collaboration.

Our group leader in the research field "Molecular quantum dynamics and stored ion beams" Apl. Prof. Andreas Wolf received the Dieter Möhl Medal Award 2021 "for his pioneering work in the use of low energy electron coolers in merging electron beams for atomic and molecular physics studies."
The award was presented during the virtual 13th International Workshop COOL 2021 externer Link on November 5, 2021.

The Dieter Möhl Medal is a award sponsored by the European Organization for Nuclear Research CERN to honor individuals who have made outstanding contributions to the development and application of particle beam cooling. It was first awarded at COOL 2013 in Mürren for the memorial of Dr. Dieter Möhl, who was one of the pioneers in the field of beam cooling and its applications.

We cordially congratulate Andreas Wolf on receiving this special scientific award.

Our division director Prof. Klaus Blaum has been selected to receive the Otto Hahn Prize 2021. Klaus Blaum is honored for his outstanding research in the field of precision physics and measurement technology that expands our knowledge of the fundamental properties of the constituents of the matter surrounding us.

Since 2005, the Otto Hahn Prize externer Link has been awarded jointly by the City of Frankfurt am Main externer Link, the Gesellschaft Deutscher Chemiker externer Link (GDCh, German Chemical Society) and the Deutsche Physikalische Gesellschaft externer Link (DPG, German Physical Society). The prize is named after the Frankfurt-born scientist Otto Hahn, who discovered nuclear fission and won the Nobel Prize in Chemistry in 1944.
According to its statute, the Otto Hahn Prize serves to "promote science, especially in the fields of chemistry, physics and applied engineering through the recognition of outstanding scientific achievements". It consists of a gold medal and a prize of 50,000 euros. The prize is awarded every two years with a ceremony in St. Paul’s Church, Frankfurt am Main, Germany, alternating each time between physics and chemistry.

The award ceremony of the Otto Hahn Prize 2021 will take place on November 5, 2021 in St. Paul’s Church, Frankfurt am Main, Germany.

We cordially congratulate Klaus Blaum on receiving this prestigious scientific award.
