An innovative particle cooling technique of the BASE collaboration has been selected to be among the Physics World Top 10 Breakthroughs in 2021 .
In 2021, our former division member Dr. Matthew Bohman and the BASE collaboration demonstrated the first sympathetic cooling of a single proton using a cryogenic two-Penning-trap system in "Nature" (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 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
has been awarded jointly by the City of Frankfurt am Main ,
the Gesellschaft Deutscher Chemiker (GDCh, German Chemical
Society) and the Deutsche Physikalische Gesellschaft (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
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.

Our former division member Dr. Jonas Karthein has been awarded the
Dissertation Prize 2021 of the Matter and Cosmos Section
(SMuK) of the German Physical Society (DPG).
The goal of the SMuK Dissertation Prize is to acknowledge the outstanding research within the scope of a dissertation and its excellent presentation in a lecture. The prize is endowed with 1.500.
Jonas Karthein received the award for his PhD thesis and the presentation entitled "Next-Generation Mass Spectrometry of Exotic
sotopes and Isomers". The prize was awarded on the SMuK Online Meeting 2021 .
The cumulative dissertation comprises the transition of the high-precision mass spectrometer ISOLTRAP at ISOLDE/CERN from the well-established Penning-trap mass spectrometry (PTMS) technique, ToF-ICR (Time-of-Flight Ion Cyclotron Resonance), to the next-generation PTMS technique, called PI-ICR (Phase-Imaging Ion Cyclotron Resonance).
We cordially congratulate Jonas on receiving this distinction of his scientific work.
Our division member Stefan Dickopf receives the Otto Haxel Prize of the Department of Physics and Astronomy of Heidelberg
University for his excellent master thesis entitled "Design, installation and characterisation of a microwave transmission
line for driving the transitions of the 3He+ hyperfine structure in a Penning trap".
The prize for the best experimental master thesis is endowed with 500 €.
We cordially congratulate Stefan on receiving this distinction of his scientific work.

Our Max Planck Fellow Professor Achim Schwenk
of TU Darmstadt has been awarded a prestigious Advanced Grant
by the European Research Council (ERC).
His research project "Exploring the Universe through Strong Interactions" (EUSTRONG) will be funded with around 2.3 million euros over a period of 5 years. The aim of the EUSTRONG project is to investigate the Strong Interaction, one of the four fundamental forces of nature, in the universe.
This is already the second ERC grant for Achim Schwenk. We cordially congratulate him on receiving this distinction!
