Advanced manufacturing (Symbolbild)

The production sector is the backbone of Europe’s industry with about 2 million companies and more than 30 million people working in this area. According to the EU, about half of all research funds are spent in this sector. There is certainly plenty of scope for research in this field: on the central challenges of digitalization and sustainability, for example. And metrological issues play a crucial role here too. To be able to bring together and promote metrological capacities, the European Association of National Metrology Institutes (EURAMET) has founded a European Metrology Network (EMN) for Advanced Manufacturing. Acting coordinator is Harald Bosse of the Physikalisch-Technische Bundesanstalt (PTB).

Prinzip des Laser-Wakefield-Beschleunigers

For decades, particle accelerators have been getting bigger and bigger. In the meantime, ring accelerators with circumferences of many kilometres have reached a practical limit. Linear accelerators in the GHz range also require very long construction lengths. For some years now, however, an alternative is explored: "tabletop particle accelerators" based on the laser excitation of charge waves in plasmas (laser wakefield). Such compact particle accelerators would be particularly interesting for future accelerator-driven light sources, but are also being investigated for high-energy physics. A team from Helmholtz-Zentrum Berlin (HZB) and the Physikalisch-Technische Bundesanstalt (PTB) has developed a method to precisely measure the cross-section of electron bunches accelerated in this way. This brings applications of these new accelerator technologies for medicine and research closer.

An overview of the diverse research landscape of PTB as well as some particularly highlighted topics (for example, PTB research surrounding the International System of Units SI) you will find in the chapter Opens internal link in current windowResearch & Development). In addition, it is always worthwhile to look at the Opens internal link in current windowmain Homepage as well as the homepages of the respective Opens internal link in current windowDivisions. How reputable PTB is among researchers you can see at Opens internal link in current windowPTB in the World of Research. Furthermore, PTB has been – specifically its R&D component, in particular – evaluated repeatedly with excellent results. You can download the respective documents (which are in German only) in the right column as a pdf file.

Scientific publications

In the database Opens internal link in current windowPTB-Publica you can search for scientific publications by PTB staff members. Furthermore, some divisions maintain their own overview lists on the publications of their staff members. These you will find via the respective Opens internal link in current windowhomepages of the divisions.

Research collaborations

The many collaborations of the individual PTB divisions you will find in the Annual Report under the column Opens internal link in current windowFrom the Divisions. International collaborations of PTB, e.g. with other metrology institutes within the framework of the European Metrology Research Programme EMRP/EMPIR, you will find at Opens internal link in current windowInternational Affairs. Some current EMRP dates you will find in the current issue of Opens internal link in current windowPTB-News.
