Preparations for a new 1 MV AMS facility in Dresden — •Johannes Lachner, Toralf Döring, Sebastian Fichter, Georg Rugel, Stephan Winkler, René Ziegenrücker, and Anton Wallner — Helmholtz-Zentrum Dresden-Rossendorf, Institute of Ion Beam Physics and Materials Research

A new AMS system called HAMSTER (Helmholtz Accelerator Mass Spectrometer Tracing Environmental Radionuclides) will be installed in Dresden-Rossendorf to expand the capabilities of radionuclide measurements at HZDR. It consists of a 1 MV pelletron tandem accelerator and has a conventional ion source for classic AMS operation and two additional injection lines: One injection line holds an ion cooler supporting isobar suppression (Ion Linear Trap for Isobar Suppression, called ILTIS), the other is a SIMS (Secondary Ion Mass Spectrometer) moved from its original location at the 6 MV DREAMS facility to continue performing Super-SIMS measurements at the new machine.

The facility will be placed in a new building that holds space for the experimental area and control room of the AMS as well as for two chemistry laboratories. Installation of the first injector beamline with the ILTIS is foreseen for early 2024 and we expect HAMSTER to be in operation by summer. In this contribution we will introduce the surrounding infrastructure and layout of the new facility.
