Development of the BAND-GEM detector solution for SANS experiments
/ Croci, Gabriele ; Muraro, Andrea ; Albani, Giorgia ; Cippo, Enrico Perelli ; Birch, Jens ; Grosso, Giovanni ; Höglund, Carina ; Hultman, Lars ; Murtas, Fabrizio ; Rebai, Marica et al.
New high count rate detectors are needed for future spallation neutron sources where large areas and high efficiency (>50%) detectors are envisaged. In this framework, GEM is one of the explored detector technologies since they feature good spatial resolution (<0.5 cm) and timing properties, have excellent rate capability (MHz/mm2) and can cover large areas (some m2) at low cost.

A new position-sensitive thermal neutron detector based on boron-coated converters has been developed as an alternative to today’s standard $^3\mathrm{He}$-based technology for application to thermal neutron scattering. The key elements of the development are the boron-coated GEM foils (Sauli in Nucl Instrum Methods Phys Res Sect A Accel Spectrom Detect Assoc Equip 386:531, 1997) that are used as a multi-layer neutron converter via the $^{10}\mathrm{B}(n,\alpha )^7\mathrm{Li}$ reaction together with an efficient collection of the produced secondary electrons.

Neutron diffraction measurements on a reference metallic sample with a high-efficiency GEM side-on $^{10}$B-based thermal neutron detector
/ Pietropaolo, A (ENEA, Frascati) ; Claps, G (ENEA, Frascati) ; Fedrigo, A (Rutherford) ; Grazzi, F (IFAC, Florence) ; Höglund, C (ESS, Lund ; Linkoping U.) ; Murtas, F (Frascati ; CERN) ; Scherillo, A (Rutherford) ; Schmidt, S (ESS, Lund ; IHI Ionbond AG, Olten) ; Schooneveld, E M (Rutherford)
The upgraded version of the GEM side-on thermal neutron detector was successfully tested in a neutron diffraction experiment on a reference sample using the INES diffractometer at the ISIS spallation neutron source, UK. The performance of the new $^{10}$B$_4$C-based detector is compared to that of a standard $^3$He tube, operating at the instrument as a part of the detectors assembly. [...]

First measurements with new high-resolution gadolinium-GEM neutron detectors
/ Pfeiffer, Dorothea (ESS, Lund ; CERN) ; Resnati, Filippo (ESS, Lund ; CERN) ; Birch, Jens (Linkoping U.) ; Etxegarai, Maddi (ESS, Lund) ; Hall-Wilton, Richard (ESS, Lund) ; Höglund, Carina (ESS, Lund) ; Hultman, Lars (Mid Sweden U., Sundsvall) ; Llamas-Jansa, Isabel (ESS, Lund) ; Oliveri, Eraldo (CERN) ; Oksanen, Esko (ESS, Lund) et al.
European Spallation Source instruments like the macromolecular diffractometer, NMX, require an excellent neutron detection efficiency, high-rate capabilities, time resolution, and an unprecedented spatial resolution in the order of a few hundred micrometers over a wide angular range of the incoming neutrons. For these instruments solid converters in combination with Micro Pattern Gaseous Detectors (MPGDs) are a promising option. [...]

Due to the Helium-3 crisis, alternatives to the standard neutron detection techniques are becoming urgent. In addition, the instruments of the European Spallation Source (ESS) require advances in the state of the art of neutron detection. [...]
