Call for Proposals 2026-II
The semester 2026-II will start on 13 July 2026 and will end on (week 29 - 27) and comprises xx weeks of Multi Bunch, 1 week of Single Bunch, and 1 week of low-alpha.
| Deadline for proposal submission - 1 March 2026, 23:59 (CET) |
Applications for instrument time may only submitted via the general access tool GATE.
Please find the list of all available instruments HERE.
PLEASE NOTE:
Unfortunately, the supply situation for liquid helium remains tense. We would like to point out that this may affect experiments that rely on liquid helium.
BESSY II - new naming scheme for instruments
As already mentioned in the last call we took the BESSY II+ upgrade as an opportunity to adapt the designations of the BESSY II beamlines. You do not need to choose both beamline and station but only the instrument. This following naming convention is used for those instruments where there are multiple stations available and where the naming of the station might not be unique (see examples below).
| Beamline | Endstation | New naming |
| BAMline | BAMline Imaging | Imaging@BAMline |
| KMC-2 | Diffraction | Diffraction@KMC-2 |
| KMC-3 XPP | CryoEXAFS | CryoEXAFS@KMC-3 |
In cases where the name of the station is unique the instrument will retain the name like MAXYMUS, mySpot, CoESCA, PEAXIS, SMART or SPEEM. The list of the new BESSY II+ instrument names (and the old ones) can be found at:

Energy Materials Facilities (EMF)
IMPORTANT for former users of ISISS, UE48_EMIL, CPMU17_EMIL and BElChem-PGM
The 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 beamtime applications in GATE for the research facility EMF. The selection of the related beamline (former: ISISS, UE48_EMIL, CPMU17_EMIL, BElChem-PGM) is no longer required. Instead, you will be asked to indicate the energy range required for your experiment. For CAT, OAESE and SISSY I the instrument scientist will allocate the appropriate beamline (UE48 or/and CPMU17) according to your specification.
Former MYSTIIC@UE48_EMIL users must submit beamtime applications in GATE for the research facility BESSY II+.
Instruments with NO availability
HIKE@KMC-1
In the effort to replace the HIKE endstation at KMC-1 with a new endstation (PRESTO), HIKE@KMC-1 will not be available in 2026-II. For more details, please contact Roberto Felix Duarte.
High-Field Diffractometer@UE46
The High-Field Diffractometer at UE46 will not be available in 2026-II. For more detailed information, please contact Eugen Weschke.
Ion Trap
Due to maintenance work the Ion Trap endstation at UE52_PGM will not be available for 2026-II. Please contact Vicente Zamudio-Bayer and Konstantin Hirsch 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.
