Induced Pressure in Positron Production Target - An Analytical and Numerical Study — •Olufemi Adeyemi1, Gudrid Moortgat-Pick1,2, and Sabine Riemann3 — 1II.

The target for positron production needs to withstand induced pressure from the energy deposited by the incident beam. In order to determine the survivability of the target impinged by the incident beam, we need to compare the computed induced stress with the ultimate tensile strength of the target material. To do this we used continuum mechanics to study the behaviour of material under intense incident beams. In this report we use both numerical and analytical methods. The results of both approaches have been compared and analyzed.
