Developing temperature simulations to optimize cluster-jet and droplet target designs — •Jost Froning, Elena Lammert, Christian Mannweiler, and Alfons Khoukaz — Institut für Kernphysik, Universität Münster, 48149 Münster, Germany

Internal hydrogen cluster-jet and droplet targets are widely applied in accelerator experiments in nuclear and particle physics. For example, both target types are to be used in the future PANDA experiment at FAIR.

Hydrogen at cryogenic temperatures is a mandatory requirement for the operation of cluster-jet and droplet targets in order to enable hydrogen liquefaction. The temperature demands on the target designs are therefore very high, so that proven design concepts have been relied on up to now. By simulating the temperature distributions of different target geometries, their performance can be predicted cost-effectively instead of constructing a new geometry without knowing its temperature behavior in advance.

This talk shows developed temperature simulations of current target designs using Autodesk CFD, comparisons between simulated and measured temperatures and optimization possibilities for future constructions.

The research project was supported by BMBF (05P21PMFP1) and the EU’s Horizon 2020 programme (824093).
