The Multi-Blade : The 10B-based neutron detector for reflectometry at ESS

The Multi-Blade detector has been designed to be used on the reflectometry instruments at the upcoming European Spallation Source. It is a 10B-based gaseous detector, built as a modular stack of multi-wire proportional chambers organised on a circle around the sample. The detector has been fully characterised. The gamma and fast-neutron sensitivity has been measured at the Source Testing Facility in Lund University, Sweden; the working capability in a reflectometry instrument has been demonstrated with measurements at CRISP in ISIS, UK; and the count-rate capability of the detector will be measured the summer of 2018 at the Budapest Neutron Centre, Hungary
