Beam Pulsing at the S-DALINAC: Superposition of the 3 GHz Beam Structure with a 1 MHz Macrostructure* — •Lennart Stobbe, Michaela Arnold, Jonny Birkhan, Uwe Bonnes, Lars Jürgensen, and Norbert Pietralla — Institut für Kernphysik, TU Darmstadt, Germany

The superconducting electron-linear-accelerator S-DALINAC provides a cw-beam with a 3 GHz time structure for different experiments. This mode is fixed and does not allow to deliver a (macro-) pulsed beam to the experimental setups. As time of flight measurements should become feasible at the so-called QCLAM magnetic spectrometer an additional pulsing device has been built and studied. The 3 GHz beam structure was superimposed with a 1 MHz macrostructure. The superposition was archived with a plate capacitor setup in the S-DALINAC’s injector-beamline. The plate capacitor deflected the beam across an aperture with a repetition rate of 1 MHz. The current state of the capacitor setup as well as the first test measurement of the macrostructure with a plastic scintillator will be presented.
