The High Energy Photon Source(HEPS) was a first fourth-generation synchrotron light source in China, it has an energy of 6 GeV and a circumference of 1360m. Construction began in 2019, and beam commissioning started on July 23,2024. The first beam circulation was achieved on the first day, proving the success of the alignment. This report will introduce the alignment strategy, and the method...

CERN surveyors have been performing the smoothing of beamlines for decades using the 2D + 1 measurement and calculation process, where computing the planimetric (XY) and altimetric (H) data is performed independently and separately. Direct leveling (1D) is still recognized today as the most efficient method to allows accurate vertical determination over long distances.

Located in the heart of the Paris-Saclay university and technology park, SOLEIL is preparing a major upgrade of its machine and beamlines. This project known as SOLEIL II aims to provide a 4th generation synchrotron light source by the end of 2030. The new storage ring will have an emittance of 85 pm.rad which will naturally arise challenging questions about the solutions to be chosen for its...

The Advanced Light Source (ALS) achieved first light in 1993. 30 years later, a major effort is taking place to upgrade it to 4th generation light source. There will be two accelerators reside in the same tunnel, one is Accumulator Ring which is hung on the inner wall, another one is Storage Ring which will replace the current ALS Storage Ring. RF system will be shared by the two Accelerators....
