The light source front ends and beamlines contain several devices designed to limit the size of, or completely stop, the photon beam. Most of these devices are meant to protect personnel and/or equipment, thus their failure would have serious implications for the facility operation. The photon beam carries extremely high energy, thus the system will experience very large thermal loads. Accurate temperature and stress distribution of these components, based on well-reasoned assumptions, is needed to accurately review the performance of these devices during the design process. Applying nonuniform heat flux as a thermal load in simulation presents a challenge. This work describes the steps of the thermomechanical numerical simulation for a typical component at the Advanced Photon Source (APS), subject to photon beam interception. The numerical algorithm used to apply the nonuniform heat flux distribution on an irregular type of surface is presented in detail. The algorithm was developed using the commercial Finite Element Analysis (FEA) software ANSYS of ANSYS, Inc.

The Advanced Photon Source (APS) is currently in the process of upgrading to a 4th generation high-energy light source. A new multi-bend achromat storage ring will provide increased brightness and an orders-of-magnitude improvement in coherent flux over the current facility. To take advantage of these new capabilities, we will be building nine new feature beamlines and implementing numerous additional beamline enhancements, all while ensuring the compatibility of existing programs. Clear challenges exist in advancing state-of-the-art optics and developing nano-resolution instrumentation. We also need to recognize and address project scheduling, labor resources, existing infrastructure, bending magnet param-eters, and possible modifications to radiation shielding in order to achieve project success.
Sub Classification should be something like General Beamline Design but option not available.
