Descripción
Wide multigap glass RPCs deployed in the miniTRASGO muon monitor, developed at LIP [1] provide a field reference for readout optimization. Continuous operation has been used to validate mechanics and HV distribution, grounding and shielding, environmental corrections, and a lightweight trajectory reconstruction chain. These lessons inform a timing-oriented architecture in which a single thin, multigap chamber [2], equipped with narrow strips and signal merging/multiplexing, dispenses with a separate thick-strip plane to reduce channel count and material [3]. Reference measurements with a double-stack system indicate operating regimes where single-plane efficiency can degrade even while timing remains competitive; planned high-voltage and power-delivery scans, together with complementary fast/slow shaping on the thin strips, are designed to isolate and mitigate these effects. The target performance is hundreds-of-picoseconds time resolution with sub-millimetre position from a simplified readout, scalable from compact telescopes to large-area Time-Of-Flight detectors. Emphasis is placed on detector engineering, readout topology and reconstruction workflow.
