The intensity of atomic beam sources has reached a limit in recent years of around 1017 atoms/s, limiting in turn the luminosity of HEP experiments utilizing polarized gas targets inside storage rings. It has been suggested that this intensity limit is a result of intra-beam scattering, although this has not been decisively proven. A method to estimate these losses, based upon the calculated beam density, has been developed. The first results are compared with data from both the molecular beam of the Ferrara SpinLab test bench and the atomic beam of the HERMES source.

Abstract
The intensity of atomic beam sources has reached a limit in recent years of around 1017 atoms/s, limiting in turn the luminosity of HEP experiments utilizing polarized gas targets inside storage rings. It has been suggested that this intensity limit is a result of intra-beam scattering, although this has not been decisively proven. A method to estimate these losses, based upon the calculated beam density, has been developed. The first results are compared with data from both the molecular beam of the Ferrara SpinLab test bench and the atomic beam of the HERMES source.File in questo prodotto:
