Commissioning of the Silicon Strip Detector (SSD) of ALICE

TL;DR

This paper reports on the commissioning process of the ALICE Silicon Strip Detector, detailing hardware status, calibration, alignment, and performance results from cosmic data, confirming its readiness for proton-proton collisions.

Contribution

It provides a comprehensive overview of the SSD commissioning, including hardware, calibration, alignment procedures, and performance validation with cosmic data.

Findings

Detector hardware is fully operational and calibrated.

Alignment procedures successfully integrated SSD with other ITS sub-detectors.

Cosmic data analysis confirms the detector's readiness for proton-proton data taking.

Abstract

The latest results from the commissioning of the SSD with cosmics are presented in this paper. The hardware status of the detector, the front-end electronics, cooling, data acquisition and issues related to the on-line monitoring are shown. In addition, the procedures implemented and followed to address the alignment with the rest of the ITS sub-detectors along with both on-line and off-line calibration strategies are described. Finally, results from simulations as well as from the reconstruction of cosmic data demonstrating the performance of the detector are presented, proving that the SSD is ready for the forthcoming proton-proton data taking.
