Calibration and improvement of the detection system CORTO
Résumé
In Nuclear Physics and High Energy Physics the calibration and debugging of new detector systems in
the early stages is possible using cosmic rays (muons). CORTO, the COsmic Ray Telescope at Orsay,
located at the Linear Accelerator Laboratory (LAL) in Orsay (France), detects and reconstructs the
position, time and direction of cosmic muons. We can study response of the investigated detectors with
using coincidences between CORTO and this detector system. This work is devoted to the measurement
of the major parameters of the facility: the X (1.8 cm) coordinate resolution and the Y (2.1 cm)
resolution, given by the time resolution for the muon track (250 ps). The paper presents the basic
principles of the track reconstruction, the electronics delays investigation and displays the results of
running.
