Characterisation and optimisation of the MDT-H droplet target — •Christian Mannweiler, Daniel Bonaventura, Jost Froning, Anna Luna Hannen, and Alfons Khoukaz for the PANDA collaboration — Universität Münster

Internal target systems enjoy widespread use in various different fields of physics, such as plasma or particle physics. A prominent example will be the P ANDA experiment at FAIR which will make use of both hydrogen cluster-jet and droplet/pellet target systems.

The operating principle of a hydrogen droplet target is to force cryogenic liquid hydrogen through a nozzle with an aperture size of around 10 microns. By inducing vibrations in the nozzle through a piezoelectric element the resultant liquid hydrogen beam is then broken up into droplets which can then propagate over ranges of several meters through vacuum.

The MDT-H is a newly constructed droplet target prototype currently set up in Münster. Through a novel, modular gas system design which allows for a higher standard of purity this target is considerably more reliable than previous designs and allows for quick progress in the characterisation and optimisation of its properties.

In our contribution we will present the MDT-H in detail and show some first results of our characterisation and optimisation endeavours.

This project has received funding from the EU Horizon 2020 programme (824093).
