Shutdown BESSY II: work has started

As of 30 July 2018, BESSY II will be down for several weeks.

In the summer shutdown, important components in the storage ring tunnel will be replaced and overhauled. The first conversion work for the BESSY VSR project also begins.  Upgrading BESSY II into a variable-pulse-length storage ring (BESSY-VSR) will provide unique experimental conditions for researchers worldwide. The shutdown lasts until 30 September 2018, and user operation will recommence on 30 October 2018.

While the ring is down, the HZB employees will be completely modifying the multipole wavelength shifter, the EDDI beamline and the radiation protection hutches. This space will be needed for installing the cold supply for the superconducting cavities in the storage ring. These are key components in the creation of BESSY VSR. Keeping them cold, however, requires an elaborate infrastructure, which is to be built up in the experimental hall over the next two years.
