Naturally, the new 4th generation machines, with their small emittances, start to bring about higher stability performance requirements, in spite of factors as high power loads, power load variation, and vibration sources. A new high-dynamics DCM (Double Crystal Monochromator) is under development at the Brazilian Light Source for the Sirius EMA beamline (Extreme Condition X-ray Methods of Analysis). In order to achieve high-bandwidth control and stability of a few nrad, as well as to prevent unpredicted mounting and clamping distortions, new solutions are proposed for crystal fixation and thermal management. Since the design is based on flexural elements, it should be indeed highly predictable, so that the work was developed using mechanical and thermal FEA, including CFD. Efforts were made to predict thermal boundaries associated with the synchrotron beam, including incident, diffracted and scattered power, for which the undulator spectrum was employed in the Monte Carlo simulation package - FLUKA *.
