Laboratory of Elementary Processes in Plasma

22PT experiment


22pt Scheme
22 Pole Trap

We continue in research with the 22-pole trap in our laboratory. This type of experiments was established by professor Dieter Gerlich. Our main aim is to study ion-molecular reactions at conditions similar to interstellar molecular clouds.
