2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/188648A novel modular high-resolution charged-particle tracking detector design using $250μm$ diameter, round, scintillating fibers and SiPM arrays for readout is presented. The fiber modules consist of 8 layers of 128 fibers, mechanically sta bilized by a carbon fiber / Rohacell foam structure. A prototype using scintillating fibers with a diameter of $300μm$ and two typ es of silicon photomultipliers has been tested in a $10GeV$ proton beam in late October 2006 at the T9 PS-beamline, CERN. We present the measured spatial resolu tion, efficiency and signal-over-noise for this setup. The advantage of this tra cker concept is a compact and modular design with low material budget and only little or no cooling requirements depending on the quality of the silicon photomultiplieres.4 pages, 7 figuresInstrumentation and Detectorstext
