VERGARA, S. et al. Characterization of the ACORDE scintillator counters using a PCI electronic card. Rev. mex. fis. [online]. 2007, vol.53, n.2, pp.120-125. ISSN 0035-001X.

We present an automatic system for performing the characterization of plastic scintillator counters to be used by ACORDE (ALICE Cosmic Ray detector). This detector consists of a 120 scintillator counter array placed on the three top faces of the ALICE magnet. In order to characterize each of those detectors, an automatic system has been implemented, consisting of three main elements: a custom-made PCI electronics card, a standard high voltage power supply, and an automatic control program, running in a PC computer. The control system has been developed within the Lab VIEW framework. The whole characterization system reaches the plateau, detector efficiency and the attenuation length of a scintillator counter in about 20 minutes.
