Development of the ACSpect neutron spectrometer: Technological advance and response against an accelerator-based neutron beam

Advances in neutron-based radiation therapies such as Boron Neutron Capture Therapy (BNCT) pushes towards the development of new neutron spectrometers, whose key features are to be their practicability, reliability, energy resolution and detection range. The ACSpect is a novel neutron spectrometer based on a two-stages monolithic silicon telescope detector coupled to an organic scintillator working as an active neutron converter.
