Computational models are an essential tool for the design, characterization, and discovery of novel materials. Hard computational tasks in materials science stretch the limits of existing high-performance supercomputing centers, consuming much of their simulation, analysis, and data resources. [...]

Surface Polishing Facility for Superconducting RF Cavities at CERN / Ferreira, Leonel (CERN) ; Chritin, Nicolas (CERN) ; Ferreira, Rodrigo (CERN) ; Gerbet, Valentin (CERN)
A new SRF cavity polishing facility which covers the needs for present projects like the HL-LHC and its CRAB cavities as well as ongoing and future activities in the frame of the FCC study was commissioned at CERN in 2019. This facility can handle chemical and electrochemical polishing baths, can process both niobium and copper-based cavities on a wide range of geometries, starting at 400 MHz up to 1.3 GHz for elliptical type of cavities and more complex shapes as defined by the DQW and RFD CRAB design. [...]

Integration of Wireless Mobile Equipment in Supervisory Application / Blanchard, Sebastien (CERN) ; Ferreira, Rodrigo (CERN) ; Gomes, Paulo (CERN) ; Pigny, Gregory (CERN) ; Rocha, Andre (CERN)
Pumping group stations and bake-out control cabinets are temporarily installed close to vacuum systems in CERN accelerator tunnels, during their commissioning. The quality of the beam vacuum during operation depends greatly on the quality of the commissioning. [...]
