After a careful assessment of the situation, the management decided that operations at HZB would be resumed step by step from 4 May onwards. Strict security regulations apply. BESSY II will be available again for in-house research from 11 May. For Sars-CoV-2-relevant measurements a fast access to BESSY II has been established.
We will continuously update the information on this page. We follow the current recommendations of the Robert Koch Institute, the Federal Ministry of Health and the Senate Chancellery and ask all parties involved for their understanding.
Gradual resumption of operations at HZB
The HZB gradually resumes operations - under permanent observation of the situation and strict security regulations.
The BESSY II accelerator will be put back into operation, but will initially only be available to HZB researchers. In the next few weeks, the laboratories will again be able to operate in a restricted manner, in accordance with safety regulations. Please contact the laboratory managers for further details.
User operation at BESSY II will be suspended until 31 May 2020. Exception: Sars-CoV-2 relevant measurements on the MX-Beamlines can be performed. For research groups we have established a fast-track access.
The patient operation in the proton therapy takes place according to plan. Should changes become necessary due to developments, all those affected will be informed.
Furthermore these measures apply:
Immediate cancellation of all events and visitor groups until 20.07.2020 in accordance with the notification of the Senate Chancellery, e.g.:
- The Long Night of Science on 6 June 2020
- Physics for breakfast on 8 July 2020 is cancelled.
- Groups of visitors cannot visit our facilities.
- School lab groups are cancelled.
- Workshops and scientific events are cancelled.
- all trainings offered by HZB company sports are cancelled.
Access for external companies: In order to ensure effective containment of the corona virus, employees of external companies may only enter HZB if they have had no contact with an infected person within the last three weeks (neither privately nor professionally). This must be confirmed in a written form (see download box). Further information can be obtained from your respective contact person at HZB.
HZB staff will get fresh information via the intranet.
- BESSY II: Phosphorous chains – a 1D material with 1D electronic propertiesFor the first time, a team at BESSY II has succeeded in demonstrating the one-dimensional electronic properties of a material through a highly refined experimental process. The samples consisted of short chains of phosphorus atoms that self-organise at specific angles on a silver substrate. Through sophisticated analysis, the team was able to disentangle the contributions of these differently aligned chains. This revealed that the electronic properties of each chain are indeed one-dimensional. Calculations predict an exciting phase transition to be expected as soon as these chains are more closely packed. While material consisting of individual chains with longer distances is semiconducting, a very dense chain structure would be metallic.
- What vibrating molecules might reveal about cell biologyInfrared vibrational spectroscopy at BESSY II can be used to create high-resolution maps of molecules inside live cells and cell organelles in native aqueous environment, according to a new study by a team from HZB and Humboldt University in Berlin. Nano-IR spectroscopy with s-SNOM at the IRIS beamline is now suitable for examining tiny biological samples in liquid medium in the nanometre range and generating infrared images of molecular vibrations with nanometre resolution. It is even possible to obtain 3D information. To test the method, the team grew fibroblasts on a highly transparent SiC membrane and examined them in vivo. This method will provide new insights into cell biology.
