Multi-scattering of Proton in Solid and Its Influence on D and T Analysis in Ti and Zr Films With PBS Method

In the PBS experiment of analyzing D and T in solid, multi-scattering of proton is innegligible. A simple linear fit method was used，which assumed that the counts of proton multi-scattering in solid were predigested as a linear function to channel, and a satisfied correction was gotten with analysis error less than 10%.
