Study of shock waves in target materials — •Olufemi Adeyemi1, Gudrid Moortgat-Pick1, Sabine Riemann2, Andriy Ushakov2, and Andreas Schälicke21II. Institute for Theoretical Physics, University of Hamburg, Luruper Chaussee 149, 22761 Hamburg — 2LC Group, DESY-Zeuthen, Platanenallee 6, 15738 Zeuthen

This study is focused on thermal shock wave development in the conversion targets of positron sources for future linear colliders. The rapid energy deposition of the intense photon (or electron) beam in the target material yields a high heat load and strong thermal stresses. It can lead to shock waves that damage the material or shorten its lifetime. We simulate the shock waves in the target material using a hydrodynamic model and investigate its contribution to the target damage.
