However, this advancement increases the number of simultaneous particle collisions. The selection of the collisions of importance is a major concern for the experimental studies. The ATLAS experiment is one of the LHC four experiments, and its current collision selection system is not enough to handle that increase of luminosity. Hence the need to develop the HGTD. This new detector will provide an additional high-precision timing information ensuring an improved selection of the interesting events. The Interlock System is one of the several safety layers ensuring the HGTD’s proper operation. It processes temperature data from the detector’s disks and generic danger signals sent by other safety systems. Within this hardware system, there is the Mon-FPGA that monitors every signal received from or transmitted to the Interlock System. The Mon-FPGA is a part of the Monitoring System that deals with the monitoring and access of the hardware system’s data. The Monitoring System is the subject of this thesis. The work presented in this thesis was developed in three parts. One includes the configuration of the monitoring hardware and the server hardware that allows to load the data collected by the former. In addition to this hardware-based system, there is the development of an user interface which accesses the server and displays the data loaded in it. These two parts together form the Monitoring System as a whole. The third part refers to the Monitoring System’s testing by simulating temperature tests at FCUL, Lisbon, and real-time temperature tests at CERN. These tests were conducted in a way that the entire Interlock System would be tested, by verifying its reaction to out-of-limit temperatures. If implemented correctly, the Monitoring System will allow to supervision the system’s reaction.application/pdfengCERNATLAS experiment (acronym of A Toroidal LHC ApparatuS)HGTD (acronym of High Granularity Timing Detector)Interlock SystemWinCC OAmaster thesis204122279
