A new detector system has been developed for the SKADI instrument at the ESS neutron source in
Sweden. The detector system is based on Li6 scintillator area detectors with multi-anode
photomultipliers. The design incorporates two movable detector housings within a vacuum tube,
allowing for measurements at various positions. The readout electronics, housed within the detector
housing, are...
The development of a new generation of neutron sources and the limited supply of 3He have led to the development of new technologies for the detection of slow neutrons. Magnetron sputtering of enriched 10B boron carbide allows for the production of homogeneous films with a density of 2.4-2.5 g/cm³. In this study, the applicability of the 10B-RPC as a slow neutron detector has been...
The helium-3 crisis sparked the development of alternative neutron detection technologies with solid converters. With their scalability, fast readout electronics, high-rate capabilities and wide range of active readout areas they are promising candidates for detectors in imaging and scattering experiments. Our group is developing three such detectors based on solid boron converters.
The...
The global shortage of Helium-3 supplies has spurred the search for alternatives to fast neutron detectors. This study proposes a detector that uses helium-4 (He-4), an abundant and stable isotope, as an alternative strobe material. Using Monte Carlo simulations with the Particle and Heavy Ion Transport Code System (PHITS) software, we evaluated the fast neutron detection performance of the...
Polyethylene-moderated 3He neutron detectors are widely used in the neutron flux monitor, fission neutron multiplicity measurement, (alpha, n), (gamma, n), and (n, xn) reaction cross-section measurements. However, this kind of detector faces a problem that their detection efficiency strongly depends on neutron emission angle and neutron energy when neutron energy rises above 1 MeV. Therefore,...
