In 1988, the AMPLEX multiplexed read-out chip used in UA2 Hybrid pixel devices, with a read-out chip “bump bonded” to the detector, were used in WA97 in the mid-1990s. By 2002, CERN had developed a bump-bonded 8000-channel pixel for the ALICE silicon-pixel detector at the LHC. Hybrid-pixel vertex detectors are now installed in the ALICE, ATLAS and CMS experiments at the LHC and the same technology is being used in the photon detectors in LHCb’s ring-imaging Cherenkov detectors.

This is 20 times more than what is possible at room temperature with ordinary copper cables of a similar cross-section. The line is composed of superconducting cables made from magnesium diboride (MgB2) and offers no resistance, enabling it to transport much higher current densities than ordinary cables, without any loss. The snag is that, in order to function in a superconducting state, the cables must be cooled to a temperature of 25 K (- 248°C) Amalia Ballarino 6/28/2019 ERICE ISSP2019 Horst Wenninger 39 6/28/2019 ERICE ISSP2019 Horst Wenninger 40 The LAA Project was extended by Council in 1996 From 1990 to 1996 the LAA Project was complemented by a CERN Detector R&D.

    CERNMarch/April 2021 cerncourier.com COURIERReporting on international high-energy physics WELCOME CERN Courier – digital edition Welcome to the digital edition of the March/April 2021 issue of CERN Courier. Hadron colliders have contributed to a golden era of discovery in high-energy physics, hosting experiments that have enabled physicists to unearth the cornerstones of the Standard Model. This success story began 50 years ago with CERN’s Intersecting Storage Rings (featured on the cover of this issue) and culminated in the Large Hadron Collider (p38) – which has spawned thousands of papers in its first 10 years of operations alone (p47). It also bodes well for a potential future circular collider at CERN operating at a centre-of-mass energy of at least 100 TeV, a feasibility study for which is now in full swing. Even hadron colliders have their limits, however. To explore possible new physics at the highest energy scales, physicists are mounting a series of experiments to search for very weakly interacting “slim” particles that arise from extensions in the Standard Model (p25). Also celebrating a golden anniversary this year is the Institute for Nuclear Research in Moscow (p33), while, elsewhere in this issue: quantum sensors HADRON COLLIDERS target gravitational waves (p10); X-rays go behind the scenes of supernova 50 years of discovery 1987A (p12); a high-performance computing collaboration forms to handle the big-physics data onslaught (p22); Steven Weinberg talks about his latest work (p51); and much more.

To my parents. A mis padres. We have seen that computer programming is an art, because it applies accumulated knowledge to the world, because it requires skill and ingenuity, and especially because it produces objects of beauty. — Donald E. Knuth [87] ACKNOWLEDGMENTS Since I finished my master’s degree and started working inthe aerospace industry with GMV I have been interested in pursuing a PhD. But I did not find the right challenge or topic I was looking for. One day I received a call from my professor from Computer Science and Engineering degree and director of the master’s degree I would later study in Leganés. He let me know about an opening position to do a PhD in High Performance Computing at CERN, in Switzerland. It was just what I was looking for; an incredible computing challenge working in the Large Hadron Collider. I applied for it and some interviews later I got the job. I have to thank first and foremost my parents. It is thanks tothem that I was able to purse any dream and challenge I ever imagined and I am ever thankful for their love and support. To my love and friend Afri, who helps me overcome any situation and makes any adventure an amazing journey to enjoy life.

Vorsitzender: 0. Prof. Bernd Brügge, PhD Prüfer der Dissertation: 1. Prof. Dr. Michael Georg Bader 2. Prof. Dr. Siegfried Bethke Die Dissertation wurde am 03.07.2017 bei der Technischen Universität München einge- reicht und durch die Fakultät für Informatik am 11.10.2017 angenommen. ABSTRACT The simulation and reconstruction of high energy physics experiments at the Large Hadron Collider (LHC) use huge customized software suites that were developed during the last twenty years. The reconstruction software of the ATLAS experiment, in particular, is challenged by the increasing amount and complexity of the data that is processed because it uses combinatorial algorithms. Extrapolations at the end of Run-1 of the LHC indicated the need of a factor 3 improvement in event processing rates in order to stay within the available resources for the workloads expected during Run-2. This thesis develops a systematic approach to analyze and optimize the ATLAS recon- struction software for modern hardware architectures. First, this thesis analyzes limita- tions of the software and how to improve it by using intrusive and non-intrusive tech- niques. This includes an analysis of the data flow graph and detailed performance meas- urements using performance counters and control flow and function level profilers.

    CERNNovember/December 2020 cerncourier.com COURIERReporting on international high-energy physics WLCOMEE CERN Courier – digital edition ADVANCING Welcome to the digital edition of the November/December 2020 issue of CERN Courier. CAVITY Superconducting radio-frequency (SRF) cavities drive accelerators around the world, TECHNOLOGY transferring energy efficiently from high-power radio waves to beams of charged particles. Behind the march to higher SRF-cavity performance is the TESLA Technology Neutrinos for peace Collaboration (p35), which was established in 1990 to advance technology for a linear Feebly interacting particles electron–positron collider. Though the linear collider envisaged by TESLA is yet ALICE’s dark side to be built (p9), its cavity technology is already established at the European X-Ray Free-Electron Laser at DESY (a cavity string for which graces the cover of this edition) and is being applied at similar broad-user-base facilities in the US and China. Accelerator technology developed for fundamental physics also continues to impact the medical arena. Normal-conducting RF technology developed for the proposed Compact Linear Collider at CERN is now being applied to a first-of-a-kind “FLASH-therapy” facility that uses electrons to destroy deep-seated tumours (p7), while proton beams are being used for novel non-invasive treatments of cardiac arrhythmias (p49). Meanwhile, GANIL’s innovative new SPIRAL2 linac will advance a wide range of applications in nuclear physics (p39). Detector technology also continues to offer unpredictable benefits – a powerful example being the potential for detectors developed to search for sterile neutrinos to replace increasingly outmoded traditional approaches to nuclear nonproliferation (p30).

  • Power for Modern Detectors
    I NTERNAT I ONAL J OURNAL OF H I G H - E NERGY P H YS I CS CERNCOURIER WELCOME V OLUME 5 8 N UMBER 9 N O V EMBER 2 0 1 8 CERN Courier – digital edition Welcome to the digital edition of the November 2018 issue of CERN Courier. Physics through Explaining the strong interaction was one of the great challenges facing theoretical physicists in the 1960s. Though the correct solution, quantum photography chromodynamics, would not turn up until early the next decade, previous attempts had at least two major unintended consequences. One is electroweak theory, elucidated by Steven Weinberg in 1967 when he realised that the massless rho meson of his proposed SU(2)xSU(2) gauge theory was the photon of electromagnetism. Another, unleashed in July 1968 by Gabriele Veneziano, is string theory. Veneziano, a 26-year-old visitor in the CERN theory division at the time, was trying “hopelessly” to copy the successful model of quantum electrodynamics to the strong force when he came across the idea – via a formula called the Euler beta function – that hadrons could be described in terms of strings. Though not immediately appreciated, his 1968 paper marked the beginning of string theory, which, as Veneziano describes 50 years later, continues to beguile physicists. This issue of CERN Courier also explores an equally beguiling idea, quantum computing, in addition to a PET scanner for clinical and fundamental-physics applications, the internationally renowned Beamline for Schools competition, and the growing links between high-power lasers (the subject of the 2018 Nobel Prize in Physics) and particle physics.

  • Discovery Machines
    DISCOVERY MACHINES CERN operates a unique complex of eight accelerators and one decelerator. The accelerators speed particles up to almost the speed of light before colliding them with each other or launching them at targets. Detectors record what happens during these collisions, and all the data collected is stored and analysed using a worldwide computing grid. Hundreds of physicists, engineers and technicians contribute to the operation and maintenance of these sophisticated machines. The LHC performed remarkably in 2016, delivering far more collisions than expected. (CERN-GE-1101021-08) 20 | CERN 2011: 6 fb-1 2012: 23 fb-1 2015: 4 fb-1 2016: 40 fb-1 7 and 8 TeV runs 13 TeV runs LHC operators at the controls in July 2016. Above, the amount of data delivered by the LHC to the ATLAS (CERN-PHOTO-201607-171-3) and CMS experiments over the course of its proton runs. These quantities are expressed in terms of integrated luminosity, which refers to the number of potential collisions during a given period. LARGE HADRON COLLIDER IN FULL SWING 2016 was an exceptional year for the Large Hadron Collider magnet, which injects the particle bunches into the machine, (LHC). In its second year of running at a collision energy of limited the number of particles per bunch. 13 teraelectronvolts (TeV), the accelerator’s performance exceeded expectations. In spite of these interruptions, the performance of the machines was excellent.
