The DUNE Far Detector Vertical Drift Technology, Technical Design Report
/ DUNE Collaboration
DUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase.

The Gas Electron Multiplier (GEM) detectors of the GE1/1 station of the CMS experiment have been operated in the CMS magnetic field for the first time on the 7$^{th}$ of October 2021. During the magnetic field ramps, several discharge phenomena were observed, leading to instability in the GEM High Voltage (HV) power system. [...]

Production and validation of industrially produced large-sized GEM foils for the Phase-2 upgrade of the CMS muon spectrometer
/ 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. [...]

/CMS Collaboration
The Compact Muon Solenoid (CMS) is a general-purpose particle detector at the Large Hadron Collider (LHC) designed to study a wide range of particles produced in high energy collisions. The interaction of the beams with the pipe, shielding and detector supporting materials can produce neutrons, photons, electrons and positrons, forming a common background radiation field for CMS detector.

Identification and reconstruction of low-energy electrons in the ProtoDUNE-SP detector
/ DUNE Collaboration
Measurements of electrons from $\nu_e$ interactions are crucial for the Deep Underground Neutrino Experiment (DUNE) neutrino oscillation program, as well as searches for physics beyond the standard model, supernova neutrino detection, and solar neutrino measurements. This article describes the selection and reconstruction of low-energy (Michel) electrons in the ProtoDUNE-SP detector. [...]

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. [...]
