Helmholtz Association supports ATHENA with 29.99 mio. euro grant
ATHENA (“Accelerator Technology HElmholtz iNfrAstructure”) is a new research and development platform focusing on accelerator technologies and drawing on the resources of all six Helmholtz accelerator institutions (DESY, Jülich Research Centre, Helmholtz Centre Berlin, Helmholtz Centre Dresden-Rossendorf HZDR, KIT and GSI with the Helmholtz Institute of Jena). The Helmholtz Association has now decided to pay almost 30 million euros towards ATHENA as a strategic development project.
“This decision demonstrates the Helmholtz Association’s strong commitment to developing and supplying ground-breaking new accelerator technologies for solving the future challenges faced by society,” says Helmut Dosch, who is the Chairman of DESY’s Board of Directors and also the spokesperson for the Helmholtz Association’s research division Matter.
Two flagship projects in accelerator research
Together, these centres want to set up two German flagship projects in accelerator research based on innovative plasma-based particle accelerators and ultramodern laser technology: an electron accelerator at DESY in Hamburg and a hadron accelerator at HZDR. At both facilities, a range of different fields of application are to be developed, ranging from a compact free-electron laser, through novel medical uses to new applications in nuclear and particle physics. As soon as they have reached the necessary level of maturity to be put to practical use in a particular area, new compact devices could be built for use in other Helmholtz centres, as well as in universities and hospitals.
HZB contributions:
Two working groups at the HZB contribute to this project: Johannes Bahrdt's Undulators Department develops and builds two novel undulators: The world's first in-vacuum apple undulator will be used at BESSY II. The second undulator, a sophisticated refined development of the prototype, will be installed at the free-electron laser in Hamburg's lighthouse project. Thorsten Kamps' group "Generation of highly brilliant electron beams" is working on a laser-based beam diagnostic device. The aim is to characterize the properties of the electron beams generated.
“The funding of the ATHENA project is an important milestone in the ARD (Accelerator Research and Development) programme, which was set up by the Helmholtz Association in 2011,” explains Reinhard Brinkmann, one of the initiators of ARD and the head of the accelerator department at DESY. Andreas Jankowiak, head of the Institute of Accelerator Physics at the HZB and spokesman for the ARD programme, adds: "Combining the competence of all Helmholtz Accelerator Centres in this way promises groundbreaking developments and new applications for ultra-compact particle accelerators.
Strengthening competitiveness in Germany and Europe
Ralph Aßmann, the project coordinator of ATHENA and lead scientists at DESY, and Ulrich Schramm, head of laser particle acceleration at HZDR, agree that “The study of new types of plasma accelerators takes place in the context of strong international competition from the US and Asia. ATHENA is consolidating the traditional leading role of Germany’s accelerator research and supporting Germany’s international competitiveness as a place for doing science.”
The work on ATHENA is closely embedded in the wider context of European research through the EU-sponsored design study EuPRAXIA, with its 40 partner institutes, which is also coordinated by DESY. Hence the top German research project ATHENA has had a clear European perspective and orientation right from the start.
Press release by DESY
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
- Solar cells on moon glass for a future base on the moonFuture settlements on the moon will need energy, which could be supplied by photovoltaics. However, launching material into space is expensive – transporting one kilogram to the moon costs one million euros. But there are also resources on the moon that can be used. A research team led by Dr. Felix Lang of the University of Potsdam and Dr. Stefan Linke of the Technical University of Berlin have now produced the required glass from ‘moon dust’ (regolith) and coated it with perovskite. This could save up to 99 percent of the weight needed to produce PV modules on the moon. The team tested the radiation tolerance of the solar cells at the proton accelerator of the HZB.
