GSI beam time 2016: NuSTAR

1. Experiments with the Ion-Catcher at the FRS (E. Haettner)

High precision experiments at low energy will be performed with the LEB of the Super-FRS at FAIR. Exotic nuclei produced and separated in-flight at high energy will be studied. A key instrument for these experiments is the Ion Catcher, a gas-filled cryogenic stopping cell in combination with a multiple reflection time-of-flight mass spectrometer. In this setup the exotic nuclei are stopped and thermalized, unambiguously identified, separated and extracted as a low energy beam of high phase-space density. This beam quality is well suited for precision measurements with traps. The Ion Catcher was successfully commissioned in several runs, especially during the 2016 beam time, at the FRS. New results and future prospects will be presented in this talk.

2. Component tests of detector systems for FAIR (H. Simon)
 
During the course of this year various different detector systems from different groups have been performed at the test facilities in Cave-C/HTD. The tests comprise highly precise time of flight systems, based on a variety of detector materials. Furthermore, an active target was brought into operation and a proton tracking system has been tested. Examples for selected systems will be presented and the necessity of these tests for the overall performance of the underlying experiments or accelerator systems will be outlined.
