Transforming targets: Adapting a cluster-jet target for use as a droplet target — •Christian Mannweiler, Daniel Bonaventura, Jost Froning, Eva-Maria Hausch, Elena Lammert, and Alfons Khoukaz — WWU, Münster, Deutschland
Internal targets such as H2 cluster-jet targets and H2 pellet targets have found widespread use in different fields of physics such as particle- and plasma physics. A prominent example is the future PANDA experiment at FAIR which will employ both target technologies for hadron physics experiments using antiproton accelerator beams.
Both types of target make use of cryogenic hydrogen in different forms. In the cluster-jet target it takes the form of a continuous beam made up of many small hydrogen clusters which achieve sizes from the nanometer scale up to several microns in diameter while a droplet target produces a stream of mono-sized, well separated hydrogen droplets at diameters in the tens of microns. Up until now, both target technologies were considered separately from each other, with a target device either creating cluster-jet beams or pellet beams. However, they remain closely related, which led us to initiate an R&D program on the development of a hybrid target which can produce both types of beam with only short downtime between swapping modes.
In our contribution we will present how we successfully transformed a cluster-jet target into a droplet target as well as first, encouraging results.
