Preparatory tests for (e,e’,γ) coincidence experiments at the S-DALINAC * — •Gerhart Steinhilber, Tobias Klaus, Norbert Pietralla, Dmytro Symochko, and Peter von Neumann-Cosel — Institut für Kernphysik, TU Darmstadt

At the Institut für Kernphysik, TU Darmstadt high resolution electron scattering experiments are performed at low momentum transfer using the Superconducting Darmstadt Linear Accelerator and electron spectrometers Lintott and QClam.

Experiments of inelastically scattered electrons in coincidence with real photons have the big advantage that the probe is purely electromagnetic and hence allows for nuclear structure studies of highest precision. In the framework of the CRC 1245 two coincidence experiments investigating the gamma-decay branching ratio of the giant dipole resonance of ^112,124Sn and the vorticity in ⁹²Zr are planned using the QClam spectrometer and a detector array consisting of 17 LaBr:Ce detectors is under construction.

During a beam time in fall 2017 three LaBr:Ce detectors have been placed around the scattering chamber of the Lintott spectrometer to test the coincidence data acquisition (DAQ). The concept of the DAQ and first results from the test will be presented.
