/ Ajuha, Sudha (Sao Paulo State U.) ; Shinoda, Ailton Akira (Sao Paulo State U.) ; Ramalho, Lucas Arruda (Sao Paulo State U.) ; Baulieu, Guillaume (IP2I, Lyon) ; Boudoul, Gaelle (IP2I, Lyon) ; Casarsa, Massimo (INFN, Trieste) ; Cascadan, Andre (Sao Paulo State U.) ; Clement, Emyr (Bristol U.) ; de Paiva, Thiago Costa (Sao Paulo State U.) ; Das, Souvik (Florida U.) et al.
We present a flexible and scalable approach to address the challenges of charged particle track reconstruction in real-time event filters (Level-1 triggers) in collider physics experiments. The method described here is based on a full-mesh architecture for data distribution and relies on the Associative Memory approach to implement a pattern recognition algorithm that quickly identifies and organizes hits associated to trajectories of particles originating from particle collisions.

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. [...]

FPGA implementation of a histogram-based parent bunch-crossing identification for the Drift Tubes chambers of the CMS experiment
/ Pozzobon, Nicola (INFN, Padua ; Padua U.) ; Montecassiano, Fabio (INFN, Padua) ; Zotto, Pierluigi (U. Padua (main) ; INFN, Padua)
/CMS Collaboration
The first running implementation on FPGA of a histogram-based trigger primitive generator for the CMS Drift Tubes at the High Luminosity LHC is presented. The foreseen architecture requires that raw charge collection times, measured for each tube by means of a TDC, are processed in the back-end to generate trigger primitives, identifying the parent bunch crossing and measuring the track parameters.

Experimental Study of Different Silicon Sensor Options for the Upgrade of the CMS Outer Tracker
/ Tracker Group of the CMS Collaboration
During the high-luminosity phase of the LHC (HL-LHC), planned to start around 2027, the accelerator is expected to deliver an instantaneous peak luminosity of up to $7.5\times10^{34}$ cm$^{-2}$s$^{-1}$. A total integrated luminosity of $3000$ or even $4000$~fb$^{-1}$ is foreseen to be delivered to the general purpose detectors ATLAS and CMS over a decade, thereby increasing the discovery potential of the LHC experiments significantly.

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.
