“…The CAST-CAPP sub-detector is making use of a novel technique called phase-matching which maximizes the detection sensitivity by combining coherently four cavities which allows for future large-scale upgrades. At the same time, each cavity is equipped with a fast frequency tuning mechanism which opens up the possibility of being sensitive also to axion streams and mini-clusters in addition to standard galactic halo axions. …”

“…Two prototype far detectors were built and operated at CERN Neutrino Platform and extensive developments are underway for improved and upgraded detectors. In order to evaluate various design alternatives and validate new concepts of light readout related to large-scale LAr detectors, we have performed several experiments with a fifty liter liquid argon TPC at CERN. …”

“…Silicon diode sensors will be used in the High-Granularity Calorimeter (HGCAL) of the upgraded CMS detector. Due to the harsh radiation environment in the HGCAL, however, the changes of the electrical properties of these diodes during irradiation and after annealing have to be studied precisely. …”

“…However, for many reasons, not the least of which is cost, all these colliders make use of existing accelerator complexes that were not built for this new task and have therefore to be upgraded. A key issue such hadron injectors have to deal with is the preservation of transverse normalised emittance. …”

“…OASIS, the Open Analog Signals Information System, extends the capabilities of the existing 'new Analogue observation system' (nAos) in many fronts : new acquisition hardware is supported to provide higher analog bandwidth to the users, a new distributed triggering scheme has been designed for greater flexibility and the software has been completely redesigned with openness in mind to allow easy upgrading and maintainability. This paper describes the architecture chosen to satisfy the new user requirements. …”
