High Granularity Digital Si-W Electromagnetic Calorimeter for Forward Direct Photon Measurements at LHC / Wang, Hongkai (Utrecht U.) /ALICE FoCal
A compact digital Si-W sampling electromagnetic calorimeter prototype using Monolithic Active Pixel Sensors (MAPS) with a granularity of $30 \times 30\, \mu \text {m}$ and a total depth of 28 $X_{0}$ has been built and tested with beams. The test beam results demonstrate not only good energy linearity and reasonable energy resolution, but also a position resolution of better than 30 ${\mu}\text {m}$ . [...]

Determining the Photon Yield of the LHCb RICH Upgrade Photo-Detection System / Blago, M P (CERN ; U. Heidelberg (main)) /LHCb RICH
For the upgrade of the LHCb RICH detectors in 2020 the existing photon detection system will be replaced. This study investigates the photon yield of the multianode photomultiplier tubes (MaPMTs), which have been proposed as the new photon detectors, together with the associated readout electronics.

Characterisation of Hamamatsu Silicon Photomultiplier Arrays for the LHCb Scintillating Fibre Tracker Upgrade / Kuonen, Axel (Ecole Polytechnique, Lausanne) ; Haefeli, Guido (Ecole Polytechnique, Lausanne) ; Girard, Olivier (Ecole Polytechnique, Lausanne) ; Stramaglia, Maria Elena (Ecole Polytechnique, Lausanne)
In the context of the LHCb detector upgrade, during the long shutdown of LHC (2019/2020), the complete tracking system will be replaced to cope with the increased luminosity and trigger less readout scheme. A large area (300  $\mathrm {m^2}$ ) scintillating fibre tracker (SciFi) with more than 500 K channels and 250  $\mu $m readout pitch is under construction. [...]

Gas Mixture Monitoring Techniques for the LHC Detector Muon Systems / Capeans, M (CERN) ; Guida, Roberto (CERN) ; Mandelli, Beatrice (CERN)
At the LHC experiments the Muon Systems are equipped with different types of gaseous detectors that will need to assure high performance until the end of the LHC run. One of the key parameters for good and safe long-term detector operation is the gas mixture composition and quality. [...]

Progress on the Upstream Tracker Electronics for the LHCb Upgrade / Abellan Beteta, Carlos (Zurich U.) /LHCb Upstream Tracker
A comprehensive upgrade of the LHCb detector is foreseen for the long shut-down of the LHC in 2019/20 (LSII). As part of the upgrade, the existing TT tracking station in front of the LHCb dipole magnet will be replaced by a new silicon micro-strip detector, the Upstream Tracker (UT). [...]

Performance Studies and Requirements on the Calorimeters for a FCC-hh Experiment / Neubüser, C (CERN) /FCC-hh Detector
The physics reach and feasibility of the Future Circular Collider (FCC) with center of mass energies up to 100 TeV and unprecedented luminosity is currently under investigation. This energy regime opens new opportunities for the discovery of new heavy particles (new gauge bosons), as well as new precise measurements in the Higgs sector (self-coupling, rare decays). [...]

A Si-PAD and Tungsten Based Electromagnetic Calorimeter for the Forward Direct Photon Measurement at LHC / Kawamura, Yota (Tsukuba U.) /ALICE FoCal
For the forward direct photon measurement at LHC-ALICE, we propose to construct a Forward Calorimeter (FoCal). FoCal-E is a silicon and tungsten calorimeter design, consists of low granularity Si-Pad layers (LGL) for precise measurement of photon energy and a few high granularity layers (HGL) with pixel readout to achieve an excellent position resolution to separate two photons from $\pi ^0$ .

Upgrade of the ATLAS Thin Gap Chamber Electronics for HL-LHC / Kawaguchi, Tomomi (Nagoya U.) /ATLAS Muon
The High-Luminosity LHC (HL-LHC) is planned to start its operation in 2026 with an instantaneous luminosity of $7.5\times 10^{34}\,\mathrm{cm}^{-2} \mathrm {s}^{-1}$ . Studies with data taken by ATLAS indicate that the upgraded first level trigger with fast tracking for HL-LHC can reduce the rate of a single muon trigger by 25% for the $p_{\mathrm {T}}$ threshold of 20 GeV while maintaining similar efficiency.
