Measurement of cosmic-muon induced neutrons with the MINIDEX experiment

Not scheduled


Dr Xiang Liu (Max-Planck-Institute for Physics)


Cosmic-muon induced neutrons are an important source of background in
low-background experiments searching for rare phenomena, like
neutrinoless double beta decay or dark matter. These neutrons can
generate radioactive isotopes in the shielding materials or in the
detector itself, creating background which can not be easily removed
by a cosmic-muon veto due to the time delay. The Muon-Induced Neutron
Indirect Detection EXperiment, MINIDEX, running in the shallow
undergound laboratory at the University of Tübingen, measures the
production of muon-induced neutrons in a variety of high-Z materials,
including lead and copper. Recently, the experiment has been upgraded
to measure the neutron production not only from through-going muons
but also from stopped muons. The design of the experiment and the
upgrade are presented as well as selected results.
