| Thermal simulation of ATLAS barrel SCT modules - II (2007) | |||||||||||||
Abstract | |||||||||||||
| A finite element thermal analysis is performed for the ATLAS barrel SCT module. The design of the module are based on the TDR model. Its several variations are also evaluated. The goal of the present calculation is to estimate the safety margin for the thermal runaway and its dependence on various design parameters. 1. Module design As a follow-up of the previous thermal simulation study on various module designs [1], two module geometries and their variations are evaluated as listed in Table 1. Model TDR-1 is the geometry proposed in the ATLAS ID TDR [2]. Model TDR-2 is a model with no BeO stiffeners (see pictures). Figure 1 shows the models TDR-1 and TDR-2. The 40 mrad tilting of stereo angle is neglected for simplicity.
