Important News about the Radiation Safety Requirements

View into the BESSY II experimental hall © HZB/M. Setzpfandt

As of 1st April 2020, the experiment hall of BESSY II will no longer be a controlled area but a surveillance area and the users are no more required to have the status as radiation workers. This makes an easier access to the experimental hall possible.

Therefore,

a radiation passport or confirmation letter is no longer needed
a radiation protection delimitation contract with HZB is no longer needed

BUT PLEASE NOTE:

The personal dosimeter (provided by HZB) and the SSR number (provided once by you) are still necessary.
The 7 days visitor regulation is still valid too.

For details please read the Radiation Safety requirements pages: radiation safety.

User research at BESSY II: Formation of a 2D meta-stable oxide in reactive environments

The chemical behaviour of solid material surfaces is an important physical characteristic for applications of catalysis, chemical sensors, fuel cells and electrodes. A research team from the Max Planck Institute for Chemical Energy Conversion has now described an important phenomenon that can occur when metal alloys are exposed to reactive environments at the synchrotron source BESSY II.

Start your accelerator tour - the Long Night of Science in a different way
Due to corona restrictions, unfortunately there will be no Long Night of Science this year. This is not only a pity for all those interested in science, but also for us! We look forward to it every year when many people come to us, asking us questions or being amazed by the huge facilities and laboratories in which we do our research. To make sure that the long night doesn't fall flat, we take you on a virtual journey through our accelerator BESSY II.

BESSY II: Experiment shows for the first time in detail how electrolytes become metallic
An international team has developed a sophisticated experimental technique at BESSY II to observe the formation of a metallic conduction band in electrolytes. To accomplish this, the team first prepared cryogenic solutions of liquid ammonia containing different concentrations of alkali metals. The colour of the solutions changes with concentration from blue to golden as the individual atoms of metal in solution transition to a metallic compound. The team then examined these liquid jets using soft X-rays at BESSY II and subsequently has been able to analyse this process in detail from the data they acquired combined with theoretical predictions. The work has been published in Science and appears even on the cover. [...]
