S. Zeiner-Gundersen and S. Olafsson have published a paper that describes their latest experimental Instrument For Rydberg Matter Research at the university of Iceland.
"The instrumental setup described here is a result of cooperation over the past three years between the University of Iceland, Norrønt AS laboratories in Norway and Leif Holmlid in Gothenburg. It has evolved greatly over these years with instrumentation built in Norway and Iceland at the same time. The Icelandic setup is mainly described here but the experimental results presented in this paper are from both laboratories"
