/ Abbas, Syed Mohsin (IPM, Tehran) ; Abbrescia, Marcello (INFN, Bari ; Bari U.) ; Abdalla, Hassan Fathy (Cairo, Acad. Sci. Res. Tech.) ; Abdelalim, Ahmed Ali (Cairo, Acad. Sci. Res. Tech.) ; Abuzeid Hassan, Shimaa Abdelwahed (INFN, Pavia) ; Aebi, Devin Michael (Texas A-M) ; Agapitos, Antonis (Peking U.) ; Ahmad, Ashfaq (Quaid-i-Azam U.) ; Ahmed, Asar (Delhi U.) ; Ahmed, Waqar (Quaid-i-Azam U.) et al.
The upgrade of the CMS detector for the high luminosity LHC (HL-LHC) will include gas electron multiplier (GEM) detectors in the end-cap muon spectrometer.
Due to the limited supply of large area GEM detectors, the Korean CMS (KCMS) collaboration had formed a consortium with Mecaro Co., Ltd. to serve as a supplier of GEM foils with area of approximately 0.6 m$^{2}$.
The consortium has developed a double-mask etching technique for production of these large-sized GEM foils.
This article describes the production, quality control, and quality assessment (QA/QC) procedures and the mass production status for the GEM foils. [...]

The series of upgrades to the Large Hadron Collider, culminating in the High Luminosity Large Hadron Collider, will enable a significant expansion of the physics program of the CMS experiment. However, the accelerator upgrades will also make the experimental conditions more challenging, with implications for detector operations, triggering, and data analysis. [...]

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. [...]

Study of the effects of radiation on the CMS Drift Tubes Muon Detector for the HL-LHC

(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.

Hochsch.) ; Sonnenschein, Lars (ADU cologne GmbH, Cologne) ; Teyssier, Daniel Francois (Aachen, Tech. Hochsch.)
The drift velocity is a key parameter of drift chambers. Its value depends on several parameters: electric field, pressure, temperature, gas mixture, and contamination, for example, by ambient air. [...]

CMS Drift Tubes performance
/ Teyssier, Daniel Francois (Aachen, Tech. Hochsch.)
/CMS Collaboration
The CMS muon barrel system includes 250 Drift Tubes (DT) stations that require 172,000 readout channels for triggering and measurement of the muon transverse momentum.
After the first Long Shutdown (LS1) of CMS, the fraction of active channels remains higher than 99\%. The spatial resolution ranges between 200 and
250 $\mathrm{\mu m}$ in the phi direction, and the intrinsic time resolution is about 2ns.
In addition the DT system showed excellent performance during Run 1, with very low associated down time and only a small fraction of data
not qualified by the data certification procedure. [...]
