Pump-probe X-ray spectroscopy at SLS 2.0

Thursday 18 Jun 2026, 09:30 → 12:40 Europe/Zurich

Grigory Smolentsev (PSI - Paul Scherrer Institut)

The aim of this online event is to inform current and prospective users about recent developments in instrumentation for pump–probe X-ray absorption and emission spectroscopy enabled by the SLS 2.0 upgrade. The event will cover measurements in the tender X-ray range at the Phoenix beamline and in the hard X-ray range at the SuperXAS beamline.

The programme will also feature several scientific talks based on pump–probe measurements carried out at SLS prior to the upgrade.

Confirmed speakers

Tender X-rays

• Philippe Wernet, Uppsala University, Sweden
• Maria Naumova, DESY, Germany

Hard X-rays

• Marcos Gil Sepulcre, University of Valencia, Spain
• Alexander Guda, Southern Federal University, Russia

Instrumentation
