Development of detector control systems for the New Small Wheel Upgrade of ATLAS experiment at CERN

This master thesis mainly refers to the design and development of control systems that are being used for the New Small Wheel Upgrade which will take place in 2020 in the ATLAS experiment of the Large Hadron Collider (LHC) at the European Organization for Nuclear Research, known as CERN. Therefore, this thesis aims to the design and the implementation of slow control systems for the (a) High Voltage validation; (b) Gas Leak validation of the Micromegas detectors; (c) the integration of the Micromegas Sector and (d) the Electronics Monitoring of both Micromegas and sTGC detectors prior to the installation in the New Small Wheel. The various control stations are developed via the WinCC Open Architecture application, which is a supervisory control and data acquisition (SCADA) and human-machine interface (HMI) system from Siemens. Main challenge of this thesis was the development of data acquisition, control and monitoring systems for several hardware, CAEN power system for low/high voltage applications, electronics boards/chips, Arduino micro-controller and Raspberry-Pi single-board computer, and for multipurpose sensors. These implementations may have various functionalities and can be used in any context, such as in experimental high energy physics or the high tech industry due to their scalability and flexibility which is the perfect choice to create solutions, including centralized control stations and geographically widely distributed systems.
