For X-ray spectroscopy applications it has been verified that Germanium detectors are enable to detect efficiently photons of considerable higher energy with respect to Silicon detectors. On the other hand, another advantage for cases like fluorescence detectors for absorption spectroscopy (XAFS), Germanium detectors do not show artifacts due to features like the escape peak interfering with interesting peaks being measured. In this context, the European project LEAPS-INNOV has launched a Research and Development program dedicated to creation of a new generation of Germanium detectors for X-ray detection. From the thermal mechanical point of view, in order to optimize the efficiency of the new Germanium detector, finite element analysis (FEA) studies have been carried out on different geometrical models. In this paper, the thermal mechanical calculations of the current prototype are presented, as well as the details of the modifications implemented since the beginning of the project, with the main objective of optimizing the operating conditions of the Germanium sensor and its associated components. For the numerical simulations, ANSYS WORKBENCH software has been used.

In the field of Particle Accelerators engineering, the design of the cooling channels of its components has been extensively based on experimental correlations for the calculation of convective heat transfer coefficients. In this scenario, this work is focused on studying whether the experimental correlations are conservative when the flow is turbulent in fully developed and non-fully developed regions. For this research, simulation models have been developed for turbulent flows in fully developed and non-fully developed regions, all of them for cooling channels with a 10 mm inner diameter. In the first case, for a circular channel, turbulence models have been studied, and comparative studies with respect to experimental correlations and previous studies performed at ALBA have been carried out. Simulation models based on the coefficients obtained from experimentally observed correlations, CFD models and an experimental validation of a mirror with inside cooling, have been performed in the second case.
