Cryobending: Deflection of frozen hydrogen filaments — •Jost Froning, Eva-Maria Hausch, Christian Mannweiler, Simon Obszerninks, and Alfons Khoukaz — Institut für Kernphysik, Universität Münster, 48149 Münster, Germany

For the use of cryogenic fibre or droplet/pellet targets at accelerator experiments in nuclear and particle physics, a way to adjust the position of the target beam at the interaction point without mechanical movement of the target components is desirable. For this purpose, a novel strategy, named cryobending, is developed and presented in this talk for a frozen hydrogen filament in vacuum. The produced hydrogen target beam is deflected by helium gas emerging from correction nozzles. A comparison between measured and expected deflection angles is shown in this talk.

Funding was received from GSI F&E (MSKHOU2023), EU Horizon 2020 programme (824093), BMBF (05P21PMFP1) and NRW Netzwerke (NW21-024-E).
