SPring-8 will be upgraded to SPring-8-II, a fourth-generation synchrotron source based on a multi-bend achromat by 2028. Electron beam energy will change from 8 GeV to 6 GeV, substantially decreasing beam emittance. The reduced emittance enables direct observation of the photon source in a beamline design, thus demanding enhanced thermal and mechanical stability in the optics. Currently, most...
MAX IV is in operation since 2015. The vacuum system is based on copper, water cooled vacuum chambers and lumped absorbers. A study was carried out to analyse the corrosion level of the water cooling channels. The aim was to determine the root causes and the possible impact on vacuum system operation. The focus was on finding pitting corrosion, since it is the most critical for creating cracks...
The European Spallation Source - ESS, has achieved its major construction in Lund, Sweden and is currently continuing parallel commissioning activities of its first systems. ESS aims to install and commission the most powerful proton LINear ACcelerator (LINAC) designed for neutron production and a 5MW Target system for the production of pulsed neutrons from spallation. In support of this...
The European Spallation Source (ESS) has made the strategic engineering choice of developing an integrated 3D model as the Single-Point-of-Truth (SPT) for engineering design, integration, manufacturing and installation. The design and integration tools along with the associated methodologies play a crucial role in the development and maintenance of ESS. This talk gives an overview of the...
In this contribution we present a compact differential pumping chamber with apertures ≥ 500 μm. It allows windowless operation for in-air sample environments as well as to connect low-quality in-vacuum sample environments to the beamline UHV vacuum section. To simplify the design, it was decided not to integrate a positioning system and to rely on machining tolerances. In the end, the assembly...
