Invited talks

Selected conferences

On 01. Feb. 1994 Prof. D. Gerlich took over the group Gasentladungs- and Ionenphysik. In addition to the traditional studies of discharges (e.g. polymerization, etching) various fundamental laboratory studies have been started. The aim was to understand in detail all kind of plasmas, ranging from technical applications to astrochemistry. Developing innovative ion guides and low temperature ion traps and combining them with lasers, molecular beams, sophisticated detectors etc., many unique experimental studies became possible.


Since his retirement (30.09.2009), Prof. D. Gerlich is actively engaged in several laboratories in Prague, Basel, Köln and other universities. Of central importance are applications of new cryogenic traps in reaction dynamics and spectroscopy.

Cryogenic 22-pole ion trap:
unique tool for astrochemistry

Using a low temperature 22-pole ion trap in Basel, we have shown that ionized Buckminsterfullerene (C60+) is present in space and that it is responsible for two Diffuse Interstellar Bands.
