ALMOND is a mobile low-flux neutron spectrometer for the LNGS underground laboratory based on a plastic scintillator array surrounded by Gd foils. It has been designed and built at KIT as a stand-alone system. In this talk, we will present the commissioning of the detector system at KIT including MC simulations of its performance, as well as first data taken underground at LNGS.
