FemtoMAX User Information

The FemtoMAX beamline is dedicated to time-resolved experiments.

Beamline contact: Website, beamline staff, Jörgen Larsson (, mobile: +46 725 17 54 54)

Currently available are the following items:

• 800 nm pump laser
• 3-10 keV X-rays
• 80 Gs, 36 GHz oscilloscope
• <2 ps timing accuracy (jitter between laser and X-rays)
• 2 Hz operation

Work in progress:

• Undulator scanning
• 10 Hz operation
• Pulse duration and pulse jitter monitoring on 100 fs level.
• Extending pump and probe spectral range
• Detector commissioning
• Procurement of MCP-PMT

Expertise for the following tasks is looked for in this call:

• Experiments where the fluorescence from different samples are measured with 100 ps temporal resolution following short X-ray pulse excitation.
• Studies of thin samples from 2D materials (graphene, ML-graphene, MAX-phase materials etc.) with limited (a few ps) temporal resolution

Limitation of the first call: Until a permit has been approved we cannot operate at higher repetition rates than 2 Hz. Our anticipation is that this will allow for feasibility tests only, but not for scientific production.

We expect the typical duration of one feasibility test to be about 2 weeks.
