Manufacturing and testing of two beam-windows prototypes


Task 3 within WP4 researches materials and assembling techniques for particle beam windows. In 
particle accelerators, a beam window is a device which separates environment at different 
pressures. Typical example is the beam windows in transfer lines, which separate atmospheric 
pressure from the beam vacuum. Such systems are complex, because they must possess thermal 
transfer properties and mechanical resistance; moreover, they must be radiation-hard, maintaining 
such properties over time under the effect of ionizing radiation.
In the scope of this deliverable, the team produced and tested under beam four beam windows 
assemblies, of different materials, characterizing their microstructure and properties before and 
after irradiation. The irradiation took place at the CERN IRRAD facilityin September-October 
2023, and the post-irradiation examination, after enough cooldown, was completed in May 2024.
