In triple-GEM detectors, the segmentation of GEM foils in electrically independent sectors allows reducing the probability of discharge damage to the detector and improving the detector rate capability; however, a segmented foil presents thin dead regions in the separation between two sectors and the segmentation pattern has to be manually aligned with the GEM hole pattern during the foil manufacturing, a procedure potentially sensitive to errors. We describe the production and characterization of triple-GEM detectors produced with an innovative GEM foil segmentation technique, the ``random hole segmentation'', that allows an easier manufacturing of segmented GEM foils.

Performance of triple-GEM detectors for the CMS Phase-2 upgrade measured in test beam
/ Pellecchia, Antonello (INFN, Bari ; U. Bari (main)) ; Verwilligen, Piet (U. Bari (main)) ; Stamerra, Anna (INFN, Bari ; U. Bari (main))
/CMS Collaboration
Triple-GEM detectors for the GE2/1 and ME0 stations of the endcap muon system for the Phase-2 upgrade of the CMS experiment have been operated in a test beam to measure their efficiency and spatial resolution, together with a high spatial resolution triple-GEM tracker. A production module of GE2/1 detectors and a prototype ME0 detector show excellent local efficiency. [...]

Development and performance of a fast timing micro-pattern gaseous detector (FTM) for future collider experiments and medical diagnostics
/ Maggi, M (INFN, Bari) ; Pellecchia, A (INFN, Bari ; Bari U.) ; Ranieri, A (Bari U.) ; Roskas, C (Gent U.) ; Sharma, A (CERN) ; Tytgat, M (Gent U.) ; Vai, I (Bergamo U. ; INFN, Pavia) ; Verwilligen, P (INFN, Bari)
The fast timing MPGD is a micro-pattern gaseous detector conceived for achieving sub-nanosecond time resolution while maintaining the ability to instrument large areas in high-rate environments; applications of such technology are perspected in high-energy physics experiments at future colliders and medical diagnostics with time-of-flight methods. The work presented is a set of systematic studies carried on an FTM prototype on the performance of GEM foils coated with resistive DLC films, whose development is essential for the FTM operation.

Rate capability of large-area triple-GEM detectors and new foil design for the innermost station, ME0, of the CMS endcap muon system

/CMS Collaboration
To extend the acceptance of the CMS muon spectrometer to the pseudorapidity region (2.4,2.8), stations of triple-GEM chambers, called ME0, are planned for the CMS Phase 2 Upgrade. These large-area, micro-pattern gaseous detectors must operate in a challenging environment with expected background particle fluxes up to 150 kHz/cm2. [...]

Layout and Assembly Technique of the GEM Chambers for the Upgrade of the CMS First Muon Endcap Station
/ CMS Muon Collaboration
Triple-GEM detector technology was recently selected by CMS for a part of the upgrade of its forward muon detector system as GEM detectors provide a stable operation in the high radiation environment expected during the future High-Luminosity phase of the Large Hadron Collider (HL-LHC). In a first step, GEM chambers (detectors) will be installed in the innermost muon endcap station in the $1.6<\left|\eta\right|<2.2$ pseudo-rapidity region, mainly to control level-1 muon trigger rates after the second LHC Long Shutdown.

ME0 project for the Triple-GEM upgrade of the CMS muon spectrometer: Design, preliminary performance and R&D; perspective
/ Fiorina, D (INFN, Pavia ; Pavia U.)
/CMS Collaboration
In the framework of the HL-LHC project, the upgrade of the CMS
Muon System envisages the installation of three new muon stations based on the
GEM technology, named as GE1/1, GE2/1 and ME0. The CMS GEM Group has
developed a novel construction design of GE1/1 triple-GEM detectors; in particular,
a new self-stretching technique has been introduced to mechanically stretch the
GEM foils without using spacer grids or glue inside the gas volume. [...]
