ABSTRACT

The aim of this project has been the evaluation of components, both hardware and

software, to be used for the Cooling System of the High Momentum Particle

Identification Detector (HMPID) for the ALICE experiment.

During the first part of my work I improved my knowledge of the main

components used in the project, namely the PT100 thermo-resistors; the Programmable

Logic Controller (PLC) SIMENS S7-300, and the OPC server-client architecture to

provide the software interface between the hardware and the user applications.In the second part I applied the acquired knowledge to the implementation and test of different schemes forthe readout and monitoring of the PT100 sensors.
