	The electron beam orbit stability is very important for the Free Electron Laser (FEL) facility. The high beam position stability requirement results in the high position stability for the FEL key components, such as quadruple magnet (Q) and beam position monitor (BPM). This work focus on the research of the dynamic performance of a mechanical support system composed of mechanical supports - including sheets and adjustments - and a granite block mounted on them. It will be applied for the beam based alignment (BBA) Q magnet and BPM for the Soft X-ray FEL project (SXFEL). The Finite-element -FE- calculations of the model characteristics were carried out to guide the subsequent tests. The test results show that the support system can meet the requirement of the SXFEL project.

	In the frame of the Extremely Brilliant Source project (EBS), studies dedicated to disturbances have been more intensively investigated. Engineering instabilities have two origins: mechanical and thermal. Major thermal issues are: - air conditioning presents a temperature ramp up of 2°C along the sector - storage ring requires a warm up period of 4 days for reaching a stable orbit These effects have been observed and corrected for 20 years. With EBS requirements, we need to identify these thermal effects in order to reduce the disturbances, thus improving more systematically the source stability. The study is lead by the comparison between the present and the new thermal system. To do so, it is necessary to evaluate the heat balance in this system, as well as to identify the thermal time constant of each component. FEA models have been performed to reveal sensitivity of these thermal issues. A full scale mock-up cell equipped with a prototype girder is measured with power cables inside. A FEA model was also developed for the present storage ring to analyse the air stream. Although investigations have already been developed, some others remain to be achieved by the end of 2016.
