This week’s user is Klavs Hansen, a pioneer in the use of electrostatic storage rings for cluster physics and a leader in the field of statistical physics of gas-phase nanoparticles. Also participating in this week’s beamtime was Vitali Zhaunerchyk from the University of Gothenberg Department of Physics. In addition to performing experiments at DESIREE, Klavs gave a rousing presentation at the joint Atomic and Chemical Physics seminar.

Who are you; where are you from?

Klavs Hansen, visiting from Tianjin University, P.R. China

What is your research in general?

Clusters.

How will your experiments at DESIREE further your research?

I came to Stockholm to measure the decay curves of anionic gold clusters, in particular their thermal radiation. It will help us paint the full picture of the life and deaths of gold clusters in gas phase.

Are there any unique capabilities of DESIREE that you are exploiting?

The extremely good staffing situation and friendly reception, together with the long storage capability of the ring.

How do you find it to work at the infrastructure?

Very pleasant, with a good group of very enthusiastic young scientists.
