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 $^{3}$He 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 $^{10}$B$_{4}$C, where neutrons are converted via the nuclear reaction $^{10}$B(n,$\alpha $)$^{7}$Li.

The micro-RWELL detector for the LHCb Muon system phase-2 upgrade
/ Bencivenni, Giovanni (CERN) ; De Oliveira, Rui (CERN) ; Felici, Giulietto (Frascati) ; Gatta, Maurizio (Frascati) ; Giovannetti, Matteo (Frascati ; Rome U., Tor Vergata) ; Morello, Gianfranco (Frascati) ; Poli Lener, M (Frascati)
The micro-RWELL is a single amplification stage resistive Micro-Pattern Gaseous Detector, realized with a copper-clad polyimide foil patterned with a micro-well matrix and coupled with the readout PCB through a DLC resistive film ($10\div100$ MOhm/$\square$).
The detector is proposed for several applications in HEP that require fast and efficient triggering in harsh environment (LHCb muon-upgrade), low mass fine tracking (FCC-ee, CepC) or high granularity imaging for hadron calorimeter applications (Muon collider).
For the phase-2 upgrade of the LHCb experiment, proposed for LHC Run-5, the excellent performance of the current muon detector will need to be maintained at 40 times the pile-up level experienced during Run-2. [...]

Production and characterization of random electrode sectorization in GEM foils
/ Pellecchia, Antonello (INFN, Bari) ; Bianco, Michele (CERN) ; De Oliveira, Rui (CERN) ; Fallavollita, Francesco (Munich, Max Planck Inst.) ; Fiorina, Davide (U. Pavia (main)) ; Rosi, Nicole (U. Pavia (main)) ; Verwilligen, Piet (INFN, Bari)
/CMS Muon Collaboration
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.
