Beamline 10.0.1

Angle- and Spin-Resolved Photoelectron Spectroscopy

Endstation 10.0.1.1 - High energy resolution spectrometer (HERS): Angle-resolved photoemission
Endstation 10.0.1.2 - Spin- and angle-resolved photoemission from solids (spin-ARPES)

Current status	Operational; open to general users
ALS-U Status	This beamline will close ~2 months before the ALS-U dark time. It is the future location of the new FLEXON Beamline, with branchlines at 10.0.1.1 and 10.0.1.2. The ALS is expanding ARPES capabilities at 4.0.3 (MERLIN) to serve current 10.0.1 users. For more information, see ALS-U Beamline Impacts and other ALS-U web pages.
