The development of the bolometer camera structural design is especially challenging because of the extreme environmental conditions within the vacuum vessel (VV) during plasma operation. Reliable measurements have to be assured while being subjected to high neutron fluxes as well as plasma radiation resulting in temperatures of the components exceeding <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$200~^{\circ }$</tex-math> </inline-formula>C. In addition to the thermal loads, the bolometer camera housing is exposed to mechanical loads caused by electromagnetic (EM) forces during transient events of the plasma operation, called disruptions. Due to the fact that the surrounding structure of the diagnostic shield module (DSM) within the upper and equatorial ports was already determined in advance, extensive design adaptation of all bolometer cameras was required. Extensive numerical analyses were carried out with the aim of achieving structural stability of the camera main body on the one hand and thermal requirements on the camera and sensors on the other hand. In a multiphysics analysis loop, several cycles were performed, starting with the EM, followed by a thermomechanical and structural analysis. In addition, the seismic and gravity loads and load scenarios, like inductive and noninductive plasma radiation as well as fatigue cycles, need to be considered. This article gives an overview of such a comprehensive analysis on the example of bolometer cameras mounted in the upper port and presents the results achieved as well as the compromises taken.
