In the field of particle accelerators, materials are routinely exposed to extreme environments, including high vacuum, intense particle irradiation, and both ultra-low and ultra-high temperatures. These demanding conditions place stringent requirements on structural and functional materials, particularly in fixed target experiments where high-energy, high-intensity proton beams are used to...

at CERN, the Linac4 accelerator is injecting 160 MeV H− beam into the 4 superposed PS Booster rings. This is achieved by a H− charge-exchange injection chicane system, using 200 µg/cm2 low density material stripping foils, to convert the negative hydrogen ions into protons by stripping off the electrons. In parallel, stripping efficiency measurements, of different foil types, are done with a...

5. Experience with CNTs at ISIS

A feasibility study of a single-wire Scanner profile Monitor (WSM) was conducted for the demonstration ring of a Fixed Field Alternating gradient (FFA) accelerator, together with the Front-End Test Stand (FETS), called FETS-FFA, as a part of the ISIS-II upgrade project. A Carbon Nano Tube (CNT) wire was selected for the FETS-FFA WSM as it is durable against heat damage from low-energy proton...
