System Development of Radiation-Tolerant Silicon Photonics Transceivers for High Energy Physics Applications / Prousalidi, Theoni (CERN ; Natl. Tech. U., Athens) ; Scarcella, Carmelo (CERN) ; Ahmed, Aalia (CERN ; York U., England, Dept. Math.) ; Detraz, Stéphane (CERN) ; Lalović, Milana (Belgrade U.) ; Olanterä, Lauri (CERN) ; Pandey, Awanish (CERN) ; Sigaud, Christophe (CERN) ; Soós, Csaba (CERN) ; Troska, Jan (CERN) et al.
Silicon photonics enables the manufacturing of high-speed, low-power, integrated optical circuits with compact footprints, and recent studies have also shown it to have a high tolerance to radiation. The technology has, therefore, been identified as an excellent candidate for the development of the next generation of radiation-tolerant optical links for high-energy physics (HEP) experiments at CERN.

A Hyperparameter Tuning Approach for an Online Log Parser / Marlaithong, Tinnakorn (KMUTT, Bangkok) ; Barroso, Vasco Chibante (CERN) ; Phunchongharn, Phond (KMUTT, Bangkok)
The European Organization for Nuclear Research (CERN) has deployed ALICE'S upgraded computing system in 2020 for improving the performance of the system. One of the aims of the upgraded computing system is to complement the monitoring system by using an Al-based logging system since logs include valuable system runtime information. [...]
