Low Density Matter at MAX IV
Research on gas phase molecules, liquids and free clusters
Investigating the interaction of light with molecules/clusters/liquids and the determination of the properties of these systems and/or the dynamics that occur under certain conditions, provides fundamental answers that are essential to the understanding of a myriad of complex processes. Such processes span the entire scientific spectrum, from branches of physics and chemistry, to engineering and biology. Some of these occur in nature whilst others are important for industrial and technological advancement.
Specific examples that greatly impact our world include ionization processes and photoreactions that take place in the upper and lower atmosphere – contributing to climate and cloud formation, reactions relevant to industry – chemical, pharmaceutical and medical, and UV radiation damage to biological molecules that is known to adversely impact human health. Many of the above fields can benefit from the information gathered from Low Density Matter Research – i.e. research using samples in the gas-, cluster-, and, liquid- phases.
Low Density Matter research at MAX IV
Low Density Matter research has a long history at MAX IV/MAX-lab and a strong and successful LDM community has been active at the lab since its inception.
A variety of cutting-edge spectroscopic methods are essential to the work of our LDM community and at MAX IV we strive to meet the experimental needs of our ever -expanding and -evolving community.
We offer access to a number of LDM-relevant beamlines (highlighted within yellow boxes below) as well as a selection of mobile scientific equipment that, when fully developed/commissioned, will be available for use at these beamlines. For more information on the LDM facilities available at MAX IV click on the links to the right.
