Accelerator and control systems expert Roland Müller received the ICALEPCS Lifetime Achievement Award. In the more than thirty years of his career at BESSY, the physicist has advanced many projects on control systems at accelerators and has been particularly committed to the international exchange of knowledge.
At this year’s "International Conference on Accelerator and Large Experimental Physics Control Systems" (ICALEPCS) in Shanghai, Roland Müller (HZB) and Andy Götz (ESRF) were jointly honored for their lifetime achievements. The ICALEPCS Lifetime Achievement Award recognizes individuals who have both made significant contributions to their field of expertise and influenced the international practice of control systems development through vision and leadership. This honor is awarded only irregularly, most recently in 2019, and is therefore a special distinction.
Over the past thirty years, Roland Müller and Andy Götz have not only led many important projects in the field of control systems to success at their own research facilities, but have also advanced the exchange in the professional community for control and operation of large physics experiments, i.e. telescopes, fusion research facilities, detectors, and especially accelerators. Thus, through great dedication and organizational skills, they have helped to build ICALEPCS into the landmark conference for control systems at large-scale research facilities.
In his acceptance speech, Müller addressed current demands on research that move him and Andy Götz, in particular the responsibility of science towards society. In consequence acquisition and storage of scientific data must be done according to FAIR principles. Data need to be Findable, Accessible, Interoperable and Repurposable. “Only sharing acquired data allows to look for results, nobody thought about at the moment the experiment was performed. The goal is a truly sustainable exploitation. It will add new scientific values. The rapid progress in fighting the Corona virus gave a glimpse into what can be achieved with a large pool of FAIR data. I am curious to see this evolve.”
Roland Müller has worked at the Berlin electron storage rings BESSY and MLS in the field of control systems since receiving his doctorate in 1988 and has held leading positions in machine operation. He retired in 2019, but continues to contribute his expertise: he is currently working on a digitization concept for BESSY III.
- HZB receives funding to make innovations usable more quicklyThe Helmholtz Association has selected three new innovation platforms that will now be funded. HZB is involved in two of them: The Innovation Platform on Accelerator Technologies HI-ACTS is intended to open up modern accelerators for a wide range of applications, while the Innovation Platform Solar TAP is intended to bring new ideas from the laboratories of photovoltaics research more quickly into an application. In total, HZB will receive 4.2 million euros in grants from the Pact for Research and Innovation over the next three years.
- Perovskite solar cells from the slot die coater - a step towards industrial productionSolar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. A team led by Prof. Dr. Eva Unger at Helmholtz-Zentrum Berlin is investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.
- Superstore MXene: New proton hydration structure determinedMXenes are able to store large amounts of electrical energy like batteries and to charge and discharge rather quickly like a supercapacitor. They combine both talents and thus are a very interesting class of materials for energy storage. The material is structured like a kind of puff pastry, with the MXene layers separated by thin water films. A team at HZB has now investigated how protons migrate in the water films confined between the layers of the material and enable charge transport. Their results have been published in the renowned journal Nature Communications and may accelerate the optimisation of these kinds of energy storage materials.
