Beamline 8.0.1

Surface and Materials Science (RIXS)

Endstation 8.0.1.1 - iRIXS
Endstation 8.0.1.2 - Beamline 8.0 Open Port
Endstation 8.0.1.3 - qRIXS (decommissioned July 2025)
Endstation 8.0.1.4 - wetRIXS

Current status	Operational; open to general users
ALS-U Status	This beamline will close at the start of the ALS-U dark time, and it will no longer host RIXS capabilities. It is the future location of the planned new Tender beamline, with imaging and scattering branchlines at 8.0.1.1 and 8.0.1.2, respectively. The ALS is expanding RIXS capabilities at 6.0.1 and 6.0.2. For more information, see ALS-U Beamline Impacts and ALS-U Timeline and Facility Impacts.
