The laser calibration system of the Obelix spectrometer

The realization of a laser-based system for calibrating the scintillator array of the Obelix spectrometer is described. The system allows a very precise timing of all the signals, which is needed for a first-level trigger based on time-of-flight information. Details of the optical system and of the...

Description
Summary:The realization of a laser-based system for calibrating the scintillator array of the Obelix spectrometer is described. The system allows a very precise timing of all the signals, which is needed for a first-level trigger based on time-of-flight information. Details of the optical system and of the calibration procedures are given.< >
