In low emittance rings, beam is quite sensitive to orbit oscillations. Fast correctors will be used to correct the beam orbit. The fast varying magnetic field will generate eddy current on the beam pipe, which will in turn change the phase and the amplitude of the magnetic field. The shielding effect of the beam pipe on a fast varying magnetic field is simulated for different frequencies. The results are also benchmarked with the measurements in the lab.

The development trend of future next-generation synchrotron light source storage rings is a compact lattice combined with small magnet apertures. This leads to important engineering challenges for the design and performance of a vacuum system because of lack of space, conductance limitation and high precision and stability positioning requirements. The speaker will review some possible solutions including the use of distributed pumping (NEG coating), distributed absorber (good thermal conducting material vacuum chamber wall), and distributed cooling (different water cooling channel design at the location where the synchrotron radiation hits the wall). In situ baking for NEG activation and precise installation will also be covered.
