FAT-GEMs: (Field Assisted) Transparent Gaseous-Electroluminescence Multipliers
/ Leardini, S. (Santiago de Compostela U., IGFAE) ; Saá-Hernández, A. (Santiago de Compostela U., IGFAE) ; Kuźniak, M. (Warsaw, Copernicus Astron. Ctr.) ; González-Díaz, D. (Santiago de Compostela U., IGFAE) ; Azevedo, C.D.R. (Aveiro U.) ; Lucas, F. (Aveiro U.) ; Amedo, P. (Santiago de Compostela U., IGFAE) ; Cortez, A.F.V. (Warsaw, Copernicus Astron. Ctr.) ; Fernández-Posada, D. (Santiago de Compostela U., IGFAE) ; Mehl, B. (CERN) et al.
The idea of implementing electroluminescence-based amplification through transparent multi-hole structures (FAT-GEMs) has been entertained for some time. Arguably, for such a technology to be attractive it should perform at least at a level comparable to conventional alternatives based on wires or meshes. [...]

Characterisation of a medium-size-area high-rate multi-layer boron-coated GEM detector for thermal neutrons
/ Cancelli, Stephanie (Milan Bicocca U. ; INFN, Milan Bicocca ; Bari U.) ; Muraro, Andrea (Bari U.) ; Murtas, Fabrizio (CERN ; Frascati) ; Cippo, Enrico Perelli (Bari U.) ; Altieri, Saverio (INFN, Pavia) ; Caruggi, Federico (Milan Bicocca U. ; INFN, Milan Bicocca) ; De Oliveira, Rui (CERN) ; Gorini, Giuseppe (Milan Bicocca U. ; INFN, Milan Bicocca ; Bari U.) ; Grosso, Giovanni (Bari U.) ; Lai, Chung-Chuan (ESS, Lund) et al.
During the last 10 years, the 3He crisis has brought to the development of new thermal neutron detection technologies and one of them is based on gas electron multiplier (GEM) principle. To detect neutrons, standard triple GEM detectors are usually coupled with a suitable converter, such as a 10B4C, where neutrons are converted via the nuclear reaction 10B(n,α)7Li. [...]

The micro-Resitive WELL (μ-RWELL) is a Micro Pattern Gas Detector (MPGD) that inherits some of the best characteristics of existing MPGDs, like GEMs and MicroMegas, while simplifying the detector construction. A significant progress towards large-scale applications has been achieved through the consolidation and industrial cost-effective manufacturing of this technology. [...]

Measurement of the effective leptonic weak mixing angle
/ LHCb Collaboration
Using pp collision data at √s=13~TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of 5.4~fb−1, the forward-backward asymmetry in the pp→Z/γ∗→μ+μ− process is measured. The measurement is carried out in ten intervals of the difference between the muon pseudorapidities, within a fiducial region covering dimuon masses between 66 and 116 GeV, muon pseudorapidities between 2.0 and 4.5 and muon transverse momenta above 20 GeV.

In the framework of the uRANIA (u-Rwell Advanced Neutron Imaging Apparatus) project, we are developing innovative thermal neutron detectors based on resistive gaseous devices such as micro-Resistive WELL (μ-RWELL) and surface Resistive Plate Counter (sRPC).The μ-RWELL is a single amplification stage resistive MPGD developed for HEP applications. The amplification stage, based on the same Apical® foil used for the manufacturing of the GEM, is embedded through a resistive layer in the readout board [...]
