Beamline I311 at MAX-lab, Lund, Sweden

Beamline I311 is an undulator based soft X-ray beamline, providing horizontally polarised light. It accommodates two end stations by using different gratings of a shared SX-700 monochromator. Starting at 42.5 eV, the upper limit of the beamline's (useable) output is around 1500 eV (600 eV for the PEEM station). A description of the common part of the beamline can be found here.

This year: a trip down memory lane. The end station is lifted in place in 1997 under supervision of a (very young) Jesper Andersen and Leif Thånell (photo: S. Sörensen).

The beamline and the spectroscopy end station have a strong liaison with the Department of Synchrotron Radiation Research at Lund University, who perform the majority of their synchrotron experiments here.

Beamtime is, however, also available to external users through submission of a proposal which is then peer reviewed by MAX-lab's Program Advisory Committee (PAC). The "Call for Proposals" normally goes out early in the calendar year, with a deadline at the beginning of March. If you are requesting beamtime on I311 for the first time, we strongly advise you to contact the person responsible for the end station you want to use prior to submitting your proposal. Please note: during the normal, weekly allocation of beamtime on the Spectroscopy station the PEEM station is also available, but only during daytime weekdays. In addition there will be about ten blocks of two days of dedicated PEEM beamtime, which again, is only available during daytime on weekdays.

Spectroscopy endstation

The spectroscopy end station is equipped with a SCIENTA SES200 analyser, set up for high resolution X-ray photoemission spectroscopy (XPS) and near edge X-ray absorption fine structure spectroscopy (NEXAFS) of samples in ultra high vacuum (UHV). Read more here.

PEEM endstation

The PEEM end station is equipped with a SPELEEM instrument for photoemission electron microscopy (PEEM), energy filtered X-PEEM as well as off-line low energy electron microscopy (LEEM). Read a little bit more here.
