Department Spin and Topology in Quantum Materials
BESSY II
User Access
Typical deadlines: twice a year in March (01/03) and September (01/09) for standard proposals for beamtime in the period ca. 6 months later.
*Special access mode: between one and several weeks per semester are reserved for proposals from quantum technology
After initial registration as a user, a two-page PDF document on the scientific context and preliminary work is required. Separately one submits one-page PDF with experimental plan. The beamlines and end stations can be selected online as well as technical parameters required. Guidelines for a beamtime application
Contact person for users from quantum technology
