The construction of Siam Photon Source II (SPS-II), Thailand’s second synchrotron light source, represents a major advancement in the nation's scientific and technological infrastructure. Designed to produce high-intensity synchrotron radiation for a wide range of applications, the project necessitates the development of advanced accelerator components. This work presents the engineering...
The Advanced Photon Source, a fourth generation light source located at Argonne National Laboratory, recently went through an upgrade where almost the entire storage ring and all the front ends were removed and either replaced or refurbished. The shutdown began in April of 2023 where all 200 girders and associated hardware were removed by the end of June. The first upgraded girder was...
While the NSLSII synchrotron is a third-generation light source providing outstanding brightness and flux, there is a robust R&D program in place to upgrade to a fourth generation, or beyond, facility. Inherent in the so-called complex-bend magnet and lattice designs are significant limitations on the beam and exit slot apertures of the vacuum chamber. These restrictions and the need for the...
The Advanced Photon Source Upgrade at Argonne National Laboratory (ANL) provides hard x-ray photon beams with a brightness 500 times greater than the original machine. A bunch lengthening cavity is used to decrease the effects of Touschek scattering (on beam lifetime) and intrabeam scattering (on beam emittance). The superconducting RF (SRF) cavity operates at 2 K in a passive, i.e....
ALS-U stability and alignment requirements coupled with tight space constraints present in the existing ALS have driven a new design for the storage ring support and alignment system. A prototype has been built and tested with alignment accuracy results in the 30 micron range and stability results in the 35 nm range. The new design overcomes distinct ergonomic challenges and reliability...
