Description
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. A concern is raised by physicists, which is if the RF system can be tuned to accommodate the circumference changes of both accelerators, especially because they are differently supported. With historical data and new survey campaign, how the circumferences change and the difference of the changes are analyzed.
