Design of a detector irradiation facility in Mainz — •Daniela Fetzer, Michael Wurm, Kai Loo, and Arshak Jafar — Johannes Gutenberg-University Mainz

Detectors for low-energy particles (MeV) are often calibrated using gamma rays to induce electron-like signals. This contribution describes Monte Carlo simulation for a new experimental array to be set up at the Detector Irradiation Facility in the Center for Fundamental Physics in Mainz. It will use a DD-neutron generator, PE moderator and a nickel (neutron,gamma) converter to produce fairly high-energy gamma rays of 9 MeV. This allows a calibration for a far wider energy range than is accessible with standard radioactive sources.

In the planned experiment, different scintillator targets will be irradiated with neutrons and gammas. In a secondary detector array, the scattered particles will then be detected and their scattering angle and energy will be compared to the incident particles and their energy deposition in the target. This talk gives an overview of the proposed experiment and its current status.
