Characterization of RPC operation with new environmental friendly mixtures for LHC application and beyond / Guida, R (CERN) ; Capeans, M (CERN) ; Mandelli, B (CERN)
The large muon trigger systems based on Resistive Plate Chambers (RPC) at the LHC experiments are currently operated with R134a based mixture. Unfortunately R134a is considered a greenhouse gas with high impact on the enviroment and therefore will be subject to regulations aiming in strongly reducing the available quantity on the market.

TORCH - Cherenkov and Time-of-Flight PID Detector for the LHCb Upgrade at CERN / Föhl, K (CERN) ; Brook, N (University Coll. London) ; Castillo García, L (CERN ; LPHE, Lausanne) ; Conneely, T (Unlisted, UK) ; Cussans, D (Bristol U.) ; Forty, R (CERN) ; Frei, C (CERN) ; Gao, R (Oxford U.) ; Gys, T (CERN) ; Harnew, N (Oxford U.) et al.
TORCH is a large-area precision time-of-flight detector, based on Cherenkov light production and propagation in a quartz radiator plate, which is read out at its edges. TORCH is proposed for the LHCb experiment at CERN to provide positive particle identification for kaons, and is currently in the Research-and-Development phase. [...]

Development of TORCH readout electronics for customised MCPs / Gao, R (Oxford U.) ; Brook, N (University Coll. London) ; García, L Castillo (CERN ; LPHE, Lausanne) ; Cussans, D (Bristol U.) ; Fohl, K (CERN) ; Forty, R (CERN) ; Frei, C (CERN) ; Gys, T (CERN) ; Harnew, N (Oxford U.) ; Piedigrossi, D (CERN) et al.
The TORCH detector is being developed for low-momentum particle identification, combining time-of-flight and Cherenkov techniques to achieve charged particle pi/K/p separation up to 10 GeV/c over a flight distance of 10m. This requires a timing resolution of 70 ps for single photons. [...]

GBT link testing and performance measurement on PCIe40 and AMC40 custom design FPGA boards / Mitra, Jubin (Calcutta, VECC) ; Khan, Shuaib A (Calcutta, VECC) ; Marin, Manoel Barros (CERN) ; Cachemiche, Jean-Pierre (Marseille, CPPM) ; David, Erno (Wigner RCP, Budapest) ; Hachon, Fr (Marseille, CPPM) ; Rethore, Fr (Marseille, CPPM) ; Kiss, Tivadar (Wigner RCP, Budapest) ; Baron, Sophie (CERN) ; Kluge, Alex (CERN) et al.
The high-energy physics experiments at the CERN's Large Hadron Collider (LHC) are preparing for Run3, which is foreseen to start in the year 2021. Data from the high radiation environment of the detector front-end electronics are transported to the data processing units, located in low radiation zones through GBT (Gigabit transceiver) links.

NaNet-10: a 10GbE network interface card for the GPU-based low-level trigger of the NA62 RICH detector / Ammendola, R (INFN, Rome2) ; Biagioni, A (INFN, Rome) ; Fiorini, M (Ferrara U. ; INFN, Ferrara) ; Frezza, O (INFN, Rome) ; Lonardo, A (INFN, Rome ; CERN) ; Lamanna, G (Frascati) ; Cicero, F Lo (INFN, Rome) ; Martinelli, M (INFN, Rome) ; Neri, I (Ferrara U. ; INFN, Ferrara) ; Paolucci, P S (INFN, Rome) et al.
A GPU-based low level (L0) trigger is currently integrated in the experimental setup of the RICH detector of the NA62 experiment to assess the feasibility of building more refined physics-related trigger primitives and thus improve the trigger discriminating power. To ensure the real-time operation of the system, a dedicated data transport mechanism has been implemented: an FPGA-based Network Interface Card (NaNet-10) receives data from detectors and forwards them with low, predictable latency to the memory of the GPU performing the trigger algorithms.

Radiation hard analog circuits for ALICE ITS upgrade / Gajanana, D (NIKHEF, Amsterdam) ; Gromov, V (NIKHEF, Amsterdam) ; Kuijer, P (NIKHEF, Amsterdam) ; Kugathasan, T (CERN) ; Snoeys, W (CERN)
The ALICE experiment is planning to upgrade the ITS (Inner Tracking System) [1] detector during the LS2 shutdown. The present ITS will be fully replaced with a new one entirely based on CMOS monolithic pixel sensor chips fabricated in TowerJazz CMOS 0.18 μ m imaging technology. [...]

The Level-0 calorimetric trigger of the NA62 experiment / Ammendola, R (Rome U., Tor Vergata) ; Barbanera, M (Perugia U.) ; Bizzarri, M (Perugia U.) ; Bonaiuto, V (Rome U., Tor Vergata) ; Ceccucci, A (CERN) ; Checcucci, B (INFN, Perugia) ; Simone, N De (Rome U., Tor Vergata ; CERN) ; Fantechi, R (CERN) ; Federici, L (Rome U., Tor Vergata ; INFN, Perugia) ; Fucci, A (CERN) et al.
The NA62 experiment at the CERN SPS aims at measuring the branching ratio of the very rare kaon decay K(+) → π(+) ν bar nu (expected 10(−)(10)) with a 10% background. Since an high-intensity kaon beam is required to collect enough statistics, the Level-0 trigger plays a fundamental role in both the background rejection and in the particle identification. [...]

High dynamic range diamond detector acquisition system for beam wire scanner applications / Sirvent, J L (CERN ; Barcelona U.) ; Dehning, B (CERN) ; Piselli, E (CERN) ; Emery, J (CERN) ; Dieguez, A (Barcelona U.)
The CERN Beam Instrumentation group has been working during the last years on the beam wire scanners upgrade to cope up with the increasing requirements of CERN experiments. These devices are used to measure the beam profile by crossing a thin wire through a circulating beam, the resulting secondary particles produced from beam/wire interaction are detected and correlated with the wire position to reconstruct the beam profile.

Test beam results of a depleted monolithic active pixel sensor using an HV-SOI process for the LH-LHC upgrade / Fernandez-Perez, S (CERN ; Barcelona, IFAE) ; Backhaus, M (CERN) ; Padilla, C (Barcelona, IFAE) ; Pernegger, H (CERN) ; Schaefer, D (CERN)
A Depleted Monolithic Active Pixel Sensor (DMAPS) on thick film SOI technology is being extensively investigated as a possible candidate for the outer layers of the ATLAS Inner Tracker in the HL-LHC upgrade. Its radiation hardness to TID (Total Ionizing Dose) and the absence of back gate effect for a dose of up to 700 Mrad was proven. [...]

Parton Showers since LEP / Richardson, Peter (CERN ; Durham U.)
We briefly discuss the development of Monte Carlo event generators over the lastfifteen years. During this period there has been a revolutionary transformationin the accuracy of these programs as matching to higher-multiplicity matrixelements and next-to-leading order calculations has become standard with thefirst next-to-next-to-leading order processes now available.
