Ανάπτυξη ηλεκτρονικού συστήματος λήψης δεδομένων και ελέγχου των αισθητήρων πυριτίου του ανιχνευτικού συστήματος Preshower του πειράματος CMS στο CERN
No full textThe subject of this thesis is the development of the electronic system for reading out the silicon strip sensors of the Preshower detector intended for use in the CMS experiment that will be held at the European Organization for Nuclear Research (CERN). Chapter 1 introduces the physics goals of the CMS experiment and the significant contribution of the Preshower detector for achieving them. Chapter 2 presents the way the front-end electronic system was designed in order to collect the charge deposited in the silicon strips by traversing charged particles. Chapter 3 deals with the development of an extremely flexible testbench which plays an essential role for the evaluation of the on-detector electronic system. Chapter 4 deals with the measurements taken from the irradiation of the silicon sensors using LASER and particle beam in order to verify the functionality of the electronic system under realistic operating conditions
A multi-channel optical plug-in module for gigabit data reception
No full textA plug-in module has been built for reception of optically transmitted data by gigabit applications. The optical receiving module is based on a 12-channel optical receiver and an FPGA with embedded high-speed deserializers. It is compatible with the serializer ASIC used by many LHC systems. Due to its compact design, several of these modules could be plugged into VME readout systems. This module will be the principle element for both the CMS Preshower data concentrator card and the TOTEM front-end driver

No full textAn efficient hardware design for rejecting common mode in a group of adjacent channels of silicon microstrip sensors used in high energy physics experiments
No full textAlgorithms have been studied using Monte Carlo techniques and implemented in a fast Xilinx Virtex II pro field programmable gate array (FPGA), in order to calculate and remove, after pedestal subtraction, the common mode of a group of adjacent channels. The implementation of the algorithms has been optimized both for speed and minimal FPGA resources, so as to be used in multi-channel applications. The aim of this work is to define the optimum algorithm for common mode calculation to be implemented for common mode rejection in the CMS Preshower detector.Ieee Transactions on Nuclear Scienc
A compact plug-in module for LHC-like trigger emulation
No full textA compact trigger emulation module for evaluating electronic systems for LHC applications has been built using off-the-shelf components. The emulator, which is based on an FPGA, generates both programmable and true-random trigger patterns in compliance with the LHC triggering rules. For the true-random trigger part, the source of randomness is the avalanche effect on a transistor emitter-base diode. The system can be used either as a plug-in module for VME systems or as a standalone device controlled via a standard USB link by a PC running LabVIEW
Single-Event Upsets in Photoreceivers for Multi-Gb/s Data Transmission
No full textA Single-Event Upset study has been carried out on p-i-n photodiodes from a range of manufacturers. A total of 22 devices of 11 types from six vendors were exposed to a beam of 63 MeV protons. The angle of incidence of the proton beam was varied between normal and grazing incidence for three data rates (1.5, 2.0 and 2.5 Gb/s)
The Gigabit Link Interface Board (GLIB), a flexible system for the evaluation and use of GBT-based optical links
No full textThe Gigabit Link Interface Board (GLIB) is an evaluation platform and an easy entry point for users of high speed optical links in high energy physics experiments. Its intended use ranges from optical link evaluation in the laboratory to control, triggering and data acquisition from remote modules in beam or irradiation tests. The GLIB is an FPGA-based Advanced Mezzanine Card (AMC) conceived to serve a small and simple system residing either inside a Micro Telecommunications Computing Architecture (mu TCA) crate, or on a bench with a link to a PC. This paper presents the architecture of the GLIB, its features as well as examples of its use in different setups
