Proven-X ARPES

The ProvenX-ARPES system is a dedicated small spot ARPES analysis tool, supporting the new ASTRAIOS 190 electron analyser with single spot shifting lens, parallel single event detectors and optional 3D spin detection, as well as the UVS µFOCAL small spot UV source with optional monochromator. The sample handling is done by the SPECS Ganymed low temperature manipulator series. The system comes with a dedicated preparation chamber, a clean UHV sample storage facility and a multi sample fast entry loadlock.

System control is done by the SpecsLab Prodigy software suite with integrated remote control packages, automated sample handling and a computer based vacuum control system.

The system can be equipped with an optional small spot x-ray source for material characterization, electron sources and charge neutralization sources. Additional software and preparation tools are available.
