Experimental study demonstrates micrometer-level tracking resolution in electron beam tests, highlighting optimal operational settings for particle detector characterization.

Key Points

To evaluate the spatial tracking performance, intrinsic sensor resolution, and optimal operational settings of EUDET-type beam telescopes equipped with MIMOSA 26 monolithic active pixel sensors.
Conducted test beam characterizations at DESY using 5 GeV and 6 GeV electron/positron beams traversing six MIMOSA 26 sensor planes.
Evaluated biased residual distributions across different beam energies, sensor spacing configurations, and sensor thresholds.
Applied iterative track fitting via the General Broken Lines formalism to quantify intrinsic sensor resolutions and calibrate multiple scattering.
Achieved a biased residual standard deviation of (2.88 ± 0.08) µm at central sensor planes in a 6 GeV beam, with a mean intrinsic resolution of (3.24 ± 0.09) µm across all six planes.
Estimated a track resolution of (1.83 ± 0.03) µm halfway between inner planes spaced 20 mm apart in a 5 GeV beam, with resolution degrading at lower energies due to multiple scattering.
Identified an optimal MIMOSA 26 operating threshold at five to six times the sensor root-mean-square noise.
