Electronics Performance of the ATLAS New Small Wheel Micromegas Wedges at CERN

A series of upgrades are planned for the LHC accelerator to increase its instantaneous luminosity to 7.5×10^34 cm−2s−1. The luminosity increase drastically impacts the ATLAS trigger and readout data rates. The present ATLAS small wheel muon detector will be replaced with a New Small Wheel (NSW) detector which is expected to be installed in the ATLAS underground cavern by the end of the Long Shutdown 2 of the LHC. With the final micromegas (MM) quadruplets (modules) already produced the activities concerning the integration of the modules into the final, fully equipped MM wedges, that will then be installed on the wheel structure on surface, are currently in full swing at CERN. One crucial part of the integration procedure concerns the installation, testing and validation of the on-detector electronics and readout chain for a very large system with a more than 2.1 M electronic channels in total. These include 4K MM FrontEnd Boards (MMFE8), custom printed circuit boards each one housing eight 64-channel VMM Application Specific Integrated Circuits (ASICs) that interface with the ATLAS Trigger and Data Acquisition (TDAQ) system through 1K data-driver cards (ADDC & L1DDC, respectively). The readout chain is based on optical link technology (GigaBit Transceiver links) connecting the backend to the front-end electronics via the Front-End LInk eXchange (FELIX), is a newly developed system that will serve as the next generation readout driver for ATLAS. Experience and performance results from the first large-scale electronics integration tests performed at CERN on final MM wedges, including system validation with cosmic-rays, are presented

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
