/ Loddo, F (INFN, Bari) ; Andreazza, A (Milan U. ; INFN, Milan) ; Arteche, F (Sao Paulo, Inst. Tech. Aeronautics) ; Barbero, M B (Marseille, CPPM) ; Barillon, P (Marseille, CPPM) ; Beccherle, R (INFN, Pisa) ; Bilei, G M (INFN, Perugia ; Perugia U.) ; Bjalas, W (CERN) ; Bonaldo, S (INFN, Padua ; Padua U.) ; Bortoletto, D (Oxford U.) et al.
The Phase-2 upgrades at the High-Luminosity LHC of ATLAS and CMS experiments at CERN will require a new tracker with readout electronics operating in extremely harsh radiation environment (1 Grad), high hit rate (3.5 GHz/cm2) and high data rate readout (5 Gb/s). The RD53 collaboration is a joint effort between the ATLAS and CMS to qualify the chosen 65 nm CMOS technology in high radiation environment and develop the pixel readout chips of both experiments.

In the context of the CERN EP R&D; on monolithic sensors and the ALICE ITS3 upgrade, the Tower Partners Semiconductor Co (TPSCo) 65 nm process has been qualified for use in high energy physics, and adopted for the ALICE ITS3 upgrade. An Analog Pixel Test Structure (APTS) featuring fast per pixel operational-amplifier-based buffering for a small matrix of four by four pixels, with a sensor with a small collection electrode and a very non-uniform electric field, was designed to allow detailed characterization of the pixel performance in this technology.

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. [...]
