Irradiation aging of the CMS Drift Tube muon detector
/ Ferrero, D.D. Redondo ; Abbiendi, G. ; Maestre, J. Alcaraz ; Fernández, A. Álvarez ; González, B. Álvarez ; Amapane, N. ; Bachiller, I. ; Barcala, J.M. ; Barcellan, L. ; Battilana, C. et al.
During the High Luminosity LHC, the Drift Tube chambers installed in the CMS detector need to operate with an integrated dose ten times higher than expected at the LHC due to the increase in integrated luminosity from 300 fb${-1}$ to 3000 fb$^{-1}$. Irradiations have been performed to assess the performance of the detector under such conditions and to characterize the radiation aging of the detector. [...]

Particle Identification Using Boosted Decision Trees in the Semi-Digital Hadronic Calorimeter Prototype
/ CALICE Collaboration
The CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) prototype using Glass Resistive Plate Chambers as a sensitive medium is the first technological prototype of a family of high-granularity calorimeters developed by the CALICE collaboration to equip the experiments of future leptonic colliders. It was exposed to beams of hadrons, electrons and muons several times in the CERN PS and SPS beamlines between 2012 and 2018. [...]

Motion of CMS detector and mechanical structures during Magnet Cycles and Stability Periods from 2008 to 2013 as observed by the Link Alignment System
/ Arce, P (Madrid, CIEMAT) ; Barcala, J M (Madrid, CIEMAT) ; Calvo, E (Madrid, CIEMAT) ; Ferrando, A (Madrid, CIEMAT) ; Josa, M I (Madrid, CIEMAT) ; Molinero, A (Madrid, CIEMAT) ; Navarrete, J (Madrid, CIEMAT) ; Oller, J C (Madrid, CIEMAT) ; Brochero, J (Cantabria U., Santander) ; Calderón, A (Cantabria U., Santander) et al.
Magnet Cycles and Stability Periods of the CMS Experiment are studied with the Alignment Link System data recorded along the 2008–2013 years of operation. The motions of the mechanical structures due to the magnetic field forces are studied and the mechanical stability of the detector during the physics data taking periods is verified..

Study of the effects of radiation on the CMS Drift Tubes Muon Detector for the HL-LHC
/ Abbiendi, G. (INFN, Bologna) ; Alcaraz Maestre, J. (Madrid, CIEMAT) ; Álvarez Fernández, A. (Madrid, CIEMAT) ; Álvarez González, B. (ICTEA, Oviedo) ; Amapane, N. (INFN, Turin ; Turin U.) ; Bachiller, I. (Madrid, CIEMAT) ; Barcala, J.M. (Madrid, CIEMAT) ; Barcellan, L. (INFN, Padua) ; Battilana, C. (INFN, Bologna ; U. Bologna (main)) ; Bellato, M. (INFN, Padua) et al.
/CMS Muon group
The CMS drift tubes (DT) muon detector, built for withstanding the LHC expected integrated and instantaneous luminosities, will be used also in the High Luminosity LHC (HL-LHC) at a 5 times larger instantaneous luminosity and, consequently, much higher levels of radiation, reaching about 10 times the LHC integrated luminosity. Initial irradiation tests of a spare DT chamber at the CERN gamma irradiation facility (GIF++), at large ($\sim$O(100)) acceleration factor, showed ageing effects resulting in a degradation of the DT cell performance.

Hadronic Energy Resolution of a Combined High Granularity Scintillator Calorimeter System
/ CALICE Collaboration
This paper presents results obtained with the combined CALICE Scintillator Electromagnetic Calorimeter, Analogue Hadronic Calorimeter and Tail Catcher & Muon Tracker, three high granularity scintillator-SiPM calorimeter prototypes. The response of the system to pions with momenta between 4 GeV/c and 32 GeV/c is analysed, including the energy response, resolution, and longitudinal shower profiles. [...]

The network of photodetectors and diode lasers of the CMS Link alignment system
/ Arce, P (Madrid, CIEMAT) ; Barcala, J M (Madrid, CIEMAT) ; Calvo, E (Madrid, CIEMAT) ; Ferrando, A (Madrid, CIEMAT) ; Josa, M I (Madrid, CIEMAT) ; Molinero, A (Madrid, CIEMAT) ; Navarrete, J (Madrid, CIEMAT) ; Oller, J C (Madrid, CIEMAT) ; Brochero, J (Cantabria U., Santander) ; Calderón, A (Cantabria U., Santander) et al.
The central feature of the CMS Link alignment system is a network of Amorphous Silicon Position Detectors distributed throughout the muon spectrometer that are connected by multiple laser lines. The data collected during the years from 2008 to 2015 is presented confirming an outstanding performance of the photo sensors during more than seven years of operation. [...]
