What is HENSA?
The High Efficiency Neutron Spectrometry Array (HENSA) is a state-of-the-art detection system for neutron background spectrometry in low radioactivity facilities, such as underground laboratories, and for the measurement of secondary neutrons produced by cosmic-rays.
Currently, the research with HENSA is focused on the study of the neutron background affecting different experiments at the Laboratorio Subterráneo de Canfranc (LSC, Spain) and the characterization of the ambient neutron background by cosmic-rays during solar cycle 25. Early versions of HENSA have been already used for neutron background measurements at the LSC and the shallow-underground laboratory Felsenkeller in Dresden, Germany.
The HENSA detector has been developed as a joint effort by researchers from different international institutions: Instituto de Física Corpuscular (IFIC/CSIC-UV, Spain), Technical University of Catalonia (INTE-UPC, Spain), Universidad Complutense de Madrid (UCM, Spain), Helmholtz-Zentrum Dresden-Rossendorf (HDZR, Germany), TRIUMF (Canada).
