Spatial resolution improvements with finer-pitch GEMs
/ Flöthner, K.J. (CERN ; Bonn U., HISKP) ; Scharenberg, L. (CERN) ; Brask, A. (Aarhus U. (main) ; CERN) ; Brunbauer, F. (CERN) ; Garcia, F. (Helsinki Inst. of Phys.) ; Janssens, D. (CERN) ; Ketzer, B. (Bonn U., HISKP) ; Lisowska, M. (CERN ; U. Paris-Saclay) ; Muller, H. (CERN ; Bonn U.) ; Oliveri, E. (CERN) et al.
Gas Electron Multipliers (GEMs) are used in many particle physics experiments, employing their 'standard' configuration with amplification holes of 140 um pitch in a hexagonal pattern. However, the collection of the charge cloud from the primary ionisation electrons from the drift region of the detector into the GEM holes affects the position information from the initial interacting particle.

Multi-Blade detector with VMM3a-ASIC-based readout: installation and commissioning at the reflectometer Amor at PSI
/ Piscitelli, F. (ESS, Lund) ; Moradi, F. Ghazi (ESS, Lund) ; Alves, F.S. (ESS, Lund) ; Christensen, M.J. (ESS, Lund) ; Hrivnak, J. (ESS, Lund) ; Johansson, A. (ESS, Lund) ; Fissum, K. (ESS, Lund) ; Lai, C.C. (ESS, Lund) ; Monera Martinez, A. (ESS, Lund) ; Pfeiffer, D. (ESS, Lund ; CERN) et al.
The Multi-Blade (MB) Boron-10-based neutron detector is the chosen technology for three instruments at the European Spallation Source (ESS): the two ESS reflectometers, ESTIA and FREIA, and the Test Beam Line. A fourth MB detector has been built, installed and commissioned for the user operation of the reflectometer Amor at PSI (Switzerland). [...]

(CUST, SKLPDE ; Hefei, CUST) et al.
Micro-Pattern Gaseous Detectors (MPGDs) with resistive anode planes provide intrinsic discharge robustness while maintaining good spatial and time resolutions. Typically read out with 1D strips or pad structures, here the characterisation results of resistive anode plane MPGDs with 2D strip readout are presented. [...]

Development of a high-rate scalable readout system for gaseous detectors

Paris-Saclay) et al.
The RD51 collaboration developed the Scalable Readout System (SRS) as part of its R&D; activities on Micro-Pattern Gaseous Detectors. This common multi-purpose readout system allows to read out small R&D; detectors (0.2k channels) up to mid-sized experiments with multiple detectors (2.5k to 5k channels). [...]

The XYU-GEM: Ambiguity-free coordinate readout of the Gas Electron Multiplier
/ Flöthner, K J (CERN ; Bonn U., HISKP) ; Janssens, D (CERN ; Brussels U., IIHE ; Vrije U., Brussels) ; Brunbauer, F (CERN) ; Ferry, S (CERN) ; Ketzer, B (Bonn U., HISKP) ; Lisowska, M (CERN ; IRFU, Saclay) ; Muller, H (CERN ; Bonn U.) ; de Oliveira, R (CERN) ; Oliveri, E (CERN) ; Orlandini, G (CERN ; Erlangen - Nuremberg U.) et al.
We describe the development of a position-sensitive Gas Electron Multiplier detector prototype, providing for each ionizing event three coordinates: the cartesian X and Y, and U at 45°. Simultaneous recording of the three projections permits ambiguity-free reconstruction of multiple tracks, and aims at operation in very high intensity radiation fields..

Removing ambiguities within a single stage becomes crucial when one can not use multiple detectors behind each other to resolve them which naturally is the case for neutral radiation. An example would be RICH detectors. [...]

The European Spallation Source (ESS) in Lund, Sweden will become the world's most powerful thermal neutron source. The Macromolecular Diffractometer (NMX) at the ESS requires three 51.2 x 51.2~cm$^{2}$ detectors with reasonable detection efficiency, sub-mm spatial resolution, a narrow point spread function (PSF) and good time resolution.
