The ATLAS luminosity monitor, LUCID (LUminosity Cherenkov Integrating Detector), had to be upgraded for the second run of LHC accelerator that started in spring 2015. increased energy proton beams and higher required a redesign cope with more demanding conditions. novelty LUCID-2 detector is it uses thin quartz windows photomultipliers as medium small amounts radioactive 207Bi sources deposited on these monitor gain stability photomultipliers. result fast accurate determination can kept...
Abstract This Technical Design Report presents a detailed description of all aspects the LUXE (Laser Und XFEL Experiment), an experiment that will combine high-quality and high-energy electron beam European with high-intensity laser, to explore uncharted terrain strong-field quantum electrodynamics characterised by both high energy intensity, reaching Schwinger field beyond. The further implications for search physics beyond Standard Model are also discussed.
The ATLAS Forward Proton (AFP) detector is intended to measure protons scattered at small angles from the interaction point. To this end, a combination of 3D Silicon pixel tracking modules and Quartz-Cherenkov time-of-flight (ToF) detectors installed 210 m away point both sides ATLAS. Beam tests with an AFP prototype combining timing sub-detectors common readout have been performed CERN-SPS test-beam facility in November 2014 September 2015 complete system integration study performance....

We present the construction of optical part ToF (time-of-flight) subdetector prototype for AFP (ATLAS Forward Proton) detector. The detector in conjunction with a 3D silicon pixel tracker will tag and measure protons originating central exclusive interactions p + → X p, where two outgoing are scattered very forward directions. is required to reduce so-called pileup backgrounds that arise from multiple proton same bunch crossing at high luminosity. background can fake signal interest, extra...
We present results of the timing performance studies optical part and front-end electronics time-of-flight subdetector prototype for ATLAS Forward Proton (AFP) detector obtained during test campaigns at CERN-SPS test-beam facility (120 GeV π+ particles) in July 2016 October 2016. The (ToF) conjunction with a 3D silicon pixel tracker will tag measure protons originating central exclusive interactions p + → X p, where two outgoing are scattered very forward directions. ToF is required to...
We present the results of our performance studies upgraded Cherenkov time-of-flight (ToF) detector for AFP (ATLAS Forward Proton) project. The latest version consists solid L-shaped fused silica bars, new customized ALD-coated micro-channel plate photomultipliers (MCP-PMTs) miniPlanacon XPM85112-S-R2D2 with an extended lifetime which operate at low gains (order 10 3 ), and updated construction. improvements were aimed to increase efficiency, as well radiation hardness has been designed in...
This report presents the boards developed for optical data transmission of calorimeter system LHCb experiment and test results. We two types boards: single-channel multi-channel ones. Multi-channel can be equipped with a variable number transmitters, depending on need, maximum allowed 12 channels. Each channel allows transmitting 32 bit at 40.08 MHz. The have been designed built using radiation hard devices produced CERN. links qualified eye diagram BERT 1.6Gbps.
This report describes the optical transmitter boards and Selection Crate, designed by Bologna INFN-LHCb group, for data transmission L0 calorimeter trigger of LHCb experiment. The transmitters are used throughout system acquisition to system. allow transmitting 32 bit at LHC clock 40.08 MHz on a single fibre. Crate (SC) is select most energetic deposits detected electromagnetic hadron calorimeters LHCb, as well evaluate other auxiliary global quantities (i.e. total energy released hit...
The ATLAS Forward Proton is a new detector system in that allows study of events with protons scattered at very small angles. final design assumes four stations distances 205 and 217 m from the interaction point on both sides exploiting Roman Pot technology. In 2016 two one arm were installed; installation other planned for 2017. This article describes details installed hardware, firmware software leading to full integration central trigger data acquisition systems.
