Solid thin targets

(page in construction)



The results presented here are mainly based on research for the interaction of a carbon fibre in high-energy hadron accelerators. The main aspects of this interaction is the damage of the target, but also beam emittance growth due to Coulomb scattering of the beam particles on the target and the parameters of the secondary particle shower generated in such interaction.

A simple python code allowing to estimate the evolution of wire tempaerature and sublimation during a beam scan is available here.
