The Mainz Advanced Neutron Gamma Observatory (MANGO), currently in the final stages of construction in Mainz, is designed as a testing facility for scintillating detector materials used in neutrino experiments, such as JUNO.
High energy photons up to 9 MeV are generated by neutron capture on a converter and subsequently Compton scattered on the detector material. Varying the selected scattering angle enables the measurement of characteristics such as the linearity of the scintillation response across a wide range of energy depositions in the target, which is an important systematic for measuring the neutrino mass ordering in JUNO.
Additionally, the neutron converter can be removed to investigate the detector response to a neutron signal. The energy deposition of the scattered neutrons can be ascertained from the time of flight to the secondary detector.
This talk will outline the current status of construction of MANGO, focusing in particular on test measurements of coincidence events in the target cell.
