Results of Linac Momentum Dump with Titanium Window for 400 MeV Protons

This report presents the results from a study of the linac momentum dump employing a Titanium (Ti 6Al-4V) window for 400 MeV protons. The setup included a 6.8” diameter stainless steel pipe positioned 350 cm upstream from the wall. Key parameters include total flux, dose equivalent, and dose residual measurements taken at various beam window configurations. The data provides critical insights into the radiation outputs and star density phenomena across different conditions, essential for optimizing safety and efficiency in proton beam applications.
