Vacuum Chamber Design for the SLS?2.0 Arcs: Challenges and Solutions

School
PARTICLES AND ACCELERATORS

Abstract:

The Swiss Light Source upgrade (SLS?2.0) represents a transition to a fourth-generation synchrotron light source, featuring a diffraction-limited storage ring with ultra-low emittance and enhanced beam quality. This upgrade imposes strict requirements on the vacuum system, especially in the arc sections where compact chambers must withstand high synchrotron radiation power and resistive-wall effects. In this talk, I will introduce the vacuum system design for the SLS?2.0 arcs, focusing on the use of ultra-thin copper chambers with NEG coatings, challenges in manufacturing and assembly, and the solutions adopted to mai ...
