Development of the Micro Pixel Chamber with DLC cathodes

MPGDs for tracking and Muon detection at future high energy physics colliders

“…In the CMS muon system additional stations, GE2/1 and ME0 [17,18], based on GEMs with high granularity and spatial segmentation, will be installed to ensure efficient matching of muon stubs to offline pixel tracks at large pseudo-rapidities during HL-LHC operation. Several solutions (µ-RWELL [19], Micro Pixel Chamber (µ-PIC) [20] and small-pad resistive Micromegas [21]) were also considered for the very forward muon tagger in the ATLAS Phase-II Upgrade Muon TDR proposal [22]. Here, the main challenges are discharge protection and miniaturization of readout elements [23], which can profit from the ongoing developments on Diamond-Like Carbon (DLC) technology [24].…”
