70 years at the high-energy frontier with the CERN accelerator complex / Brüning, Oliver (CERN) ; Klein, Max (Liverpool U.) ; Myers, Stephen (CERN) ; Rossi, Lucio (Milan Bicocca U. ; LASA, Segrate)
Over the first 70 years of its existence, CERN has created an impressive portfolio of accelerators, many of which are still in operation today. The ‘jewel in the crown’ of the complex is certainly the 27-km tunnel and its infrastructure, built approximately 100 m underground between the Jura mountains and Lake Geneva on the French–Swiss border.

Highly uniform silicon nanopatterning with deep-ultraviolet femtosecond pulses / Granados, Eduardo (CERN) ; Martinez-Calderon, Miguel (CERN) ; Groussin, Baptiste (CERN) ; Colombier, Jean Philippe (Lab. Hubert Curien, St. Etienne) ; Santiago, Ibon
Abstract The prospect of employing nanophotonic methods for controlling photon–electron interactions has ignited substantial interest within the particle accelerator community. Silicon-based integrated dielectric laser acceleration (DLA) has emerged as a viable option by leveraging localized photonic effects to emit, accelerate, and measure electron bunches using exclusively light.

New RPC gas mixtures for sustainable operation in the CMS experiment / López, Dayron Ramos (INFN, Bari ; Bari Polytechnic) /CMS Muon Collaboration
The current operation of the Resistive Plate Chamber (RPC) system within the CMS experiment involves approximately 95% tetrafluoroethane (C2H2F4, TFE). However, in response to climate change concerns, the European Union has instituted a ban on TFE owing to its elevated Global Warming Potential (GWP), resulting in an associated increase in market prices.

Recent results and perspectives of the Monopix Depleted Monolithic Active Pixel Sensors (DMAPS) / Hügging, Fabian (Bonn U.) ; Barbero, Marlon (Marseille, CPPM) ; Barrilon, Pierre (Marseille, CPPM) ; Bespin, Christian (Bonn U.) ; Breugnon, Patrick (Marseille, CPPM) ; Caicedo, Ivan (Bonn U.) ; Degerli, Yavuz (IRFU, Saclay) ; Dingfelder, Jochen (Bonn U.) ; Hemperek, Tomasz (Bonn U.) ; Hirono, Toko (Bonn U.) et al.
The integration of readout electronics and sensors into a single entity of silicon in monolithic pixel detectors lowers the material budget while simplifying the production procedure compared to the conventional hybrid pixel detector concept. The increasing availability of high-resistivity substrates and high-voltage capabilities in commercial CMOS processes facilitates the application of depleted monolithic active pixel sensors (DMAPS) in modern particle physics experiments.

Dark-Sector Search via Pion-Produced η and η′ Mesons Decaying Invisibly in the NA64h Detector / NA64 Collaboration
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η′ mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π- on nuclei of an active target as the source of neutral mesons. [...]
