Data quality monitor as the final quality assurance procedure for the ALICE-TOF detector

All the steps which led to the construction of the ALICE-TOF detector were strictly followed by a set of quality assurance procedures to guarantee high and uniform performances. Once a module of the detector (whose basic element is the Multigap Resistive Plate Chamber) is assembled, a final test concerning the data readout applies. While the detector is taking data, both during test and physics runs, a check of the quality of the data is needed. For this purpose some monitoring tools have been developed. These tools have been used since the beginning of the TOF commissioning and finally they have also been successfully used during the first global data-taking test-runs of ALICE.
