BESSY II+ upgrade - new naming scheme for the instruments
BESSY II has now been in operation for more than 20 years and will remain in operation at least until 2035. Keeping BESSY II at the forefront of science and technology development requires the transition from a unique and highly productive analytical tool towards a materials discovery and innovation hub. With a clear focus on operando methods for energy research, and along the chain “generation of light, use of light, data generation, data handling”, BESSY II+ will provide new possibilities for our research, our users, and our partners.
We are taking the BESSY II+ upgrade as an opportunity to adapt the designations of the BESSY II+ beamlines. In recent years, the trend has shifted away from flexible endstations. It is time to reflect this in the naming convention. Starting with this Call for Proposals 2026-I you will no longer have to choose both beamline and station but only the instrument.
Examples:
- BAMLine + BAMline Imaging => Imaging@BAMline
- KMC-3 XPP + CryoEXAFS => CryoEXAFS@KMC-3
- KMC-2 + Diffraction => Diffraction@KMC-2
This naming convention is used for those instruments where there are multiple stations available and where the naming of the station might not be unique.
In cases where the name of the station is unique the instrument will retain the name like
- MAXYMUS
- CoESCA
- PEAXIS

Energy Materials Facilities (EMF)
| IMPORTANT for former users of ISISS, UE48_EMIL, CPMU17_EMIL and BElChem-PGM |
The new Energy Materials Facilities (EMF) are dedicated to the research of energy materials and comprises the instruments (former: endstations)
| CAT | ECCOS | ISISS | OAESE |
PINK |
SISSY I |
Users who plan to use one of these instruments must submit applications in GATE for EMF. The selection of the related beamline (former: ISISS, UE48_EMIL, CPMU17_EMIL, BElChem-PGM) is no longer required.
Instrument with limited availability
At ECCOS@BElChem-PGM the spectrometer will be replaced. Due to installation and commissioning of the new specrometer, ECCOS will not be available for user operation for a few weeks in 2026-I. Please contact Michael Hävecker (michael.haevecker@helmholtz-berlin.de) for more detailed information.
New instruments in user operation
The new beamline UE51_PGM-2 will be open for user operation for the first time and the instruments SOL³PES@myOPUS and LiXEdrom@myOPUS are available. Please contact the instrument scientists Robert Seidel, Ronny Golnak and Jie Xiao for more detailed information.
Transnational access support through NEPHEWS
Strategic access for quantum technology (STRAQTECH)
In the framework of the LEAPS-INNOV activity STRAQTECH we explicitly are inviting beamtime applications from the research field of Quantum Technology for the instruments GELEM Dipole (soft-x-ray photoemission and absorption) and SPEEM (photoemission electron microscopy with variable light polarization). Please contact Anna Makarova (quantum@helmholtz-berlin.de) for more detailed information.
