 Beam-dynamic effects at the CMS BRIL van der Meer scans / Babaev, Anton (TOMSK-POLYTEC) /CMS Collaboration The CMS Beam Radiation Instrumentation and Luminosity Project (BRIL) is responsible for the simulation and measurement of luminosity, beam conditions and radiation fields in the CMS experiment. The project is engaged in operating and developing new detectors (luminometers), adequate for the experimental conditions associated with high values of instantaneous luminosity delivered by the CERN LHC.

 Photon-photon measurements in CMS / Chudasama, Ruchi (Bhabha Atomic Res. Ctr.) /CMS Collaboration We discuss the measurement of photon-photon processes using data collected by the CMS experiment in pp collisions at $\sqrt{s}$ = 7 and 8 TeV and in PbPb collisions at $\sqrt{s_{_{{\rm NN}}}}= 5.02$ TeV..

 CMS Pixel detector development for the HL-LHC / Schwandt, Joern (Hamburg U.) /CMS Collaboration An upgrade program is underway which will bring the luminosity of the LHC up to about 7.5x10$^{34}$ cm$^{-2}$s$^{-1}$ in 2027, with the goal of an integrated luminosity of 3000~fb$^{-1}$ by the end of 2037. This High Luminosity scenario, HL-LHC, will present new challenges of higher data rates and increased radiation hardness for the pixel detector (a non-ionizing fluence of 2x10$^{16}$~n$_{eq}$/cm$^2$ and an ionizing dose of 10~MGy, is expected on the inner pixel layer for 3000~fb$^{-1}$ integrated luminosity).

 Silicon-Based Detectors at the HL-LHC / Hartmann, Frank (KIT, Karlsruhe, EKP) /ALICE,ATLAS,CMS and LHCB Collaborations This document discusses the silicon-based detectors planned for the High Luminosity LHC. The special aspects to cope with the new environment and its challenges, e.g. [...] CMS-CR-2018-015.- Geneva : CERN, 2018 - 12 p.

 MD#1826: Measurement of Quench Heater vertical kick / Valette, Matthieu (CERN) ; Wollmann, Daniel (CERN) ; Lindstrom, Bjorn Hans Filip (Uppsala University (SE)) ; Bortot, Lorenzo (CERN) ; Fernandez Navarro, Alejandro (CERN) ; Schmidt, Rudiger (Technische Universitaet Darmstadt (DE)) ; Verweij, Arjan (CERN) Following the observation of vertical orbit oscillations of the LHC beam between the detection of a (beam induced) quench of an LHC main dipole and the beam dump, a study was started to verify that the orbit distortions are caused by the firing of the quench heaters (QH).
