SESAME started operation in January 2017. In order to receive heat deposited in various synchrotron devices during operation, a low-conductivity water cooling system was installed. Within this paper the design, construction and operation of the water cooling system will be discussed, Both Hydraulic and Thermal Behavior of the system will be analyzed and discussed with numerical simulation means as well as real operation pressure and temperature data for the purpose of a better understanding of the cooling system

  AM technology (3D Printing) in plastics and metals has now been in commercial use for over 30 years. However, the application of this technology in vacuum environments has been limited, due to the material porosity and additives used in the manufacturing techniques. This paper reports on the testing and use of FDM (Fused Deposition Modelling) PEEK and DMLS (Direct Metal Laser Sintering) metal components inside a UHV environment. Specifically covering the use of DMLS to successfully produce a complex vacuum vessel operating at 10-6 mbar, as used on the new VMXm beamline at Diamond Light Source. Vacuum testing the vessel has demonstrated that this manufacturing technique has the potential to produce vessels that are capable of holding 10-10mbar.

  Pohang Accelerator Laboratory (PAL) has developed a SASE X-ray Free Electron Laser based on 10 GeV linear accelerator. The inter-Undulator (IU) support section was developed to be used in the intersections of the Undulator Systems. The IU supports consist of phase shifter, quadrupole magnet with mover, beam loss monitor, cavity BPM with mover, two corrector magnets and vacuum components. The adjusting mechanism of IU Support has manual alignment system to be easily adjusting the component. The mover of quadruple magnet and cavity BPM with submicron repeatability has auto-adjusting systems with stepping motor. The mover main specifications include compact dimensions and a ±1.5 mm stroke in the vertical and horizontal direction. Linear motion guide based on 5-phase stepping motors have been chosen. This paper describes the design of the stages used for precise movement and results of mechanical measurements including reproducibility will be reported.
