Performances of superconducting accelerating cavities, in particular made of bulk Niobium, depend on the purity and crystallographic quality of the material exposed to an intense radio-frequency electromagnetic field. The preparation of the cavity walls has been and is still one of the major challenges in SRF accelerator technology. In order to avoid performance degradation, the damaged layer...

The ERC Advanced Grant COXINEL aims at demonstrating free electron laser amplification, at a resonant wavelength of 200 nm, based on a laser plasma acceleration source. To achieve the amplification, a 8 m long dedicated transport line was designed to manipulate the beam qualities. It starts with a triplet of permanent magnet with tunable gradient quadrupoles (QUAPEVA) that handles the highly...

The emittance is an essential feature to measure for an accelerator beam. It describes the behavior of the beam at each longitudinal position. For the time, the Alisson scanner is the most used system to qualify the emittance of a proton beam. However, this type of measurement has a default: it is a two-dimensions diagnostic. It means that it can only measure the position and angular...

Pulsating Heat Pipes (PHP) are two-phase heat transfer devices consisting of a long capillary tube bent into many U-turns connecting the cold source to the hot source. They are thermally driven by an oscillatory flow of liquid slugs and vapor plugs. Due to their lightness, simple configuration and thermal performance, PHP are excellent candidates to be used as thermal links between...
