Description
ALBA is a 3rd generation synchrotron with ten years of operation. During this period, 10 beamlines have been placed in proper functioning and four more are in installation and design phase. Along these ten years, several misalignments have been detected and measured in the accelerators complex, however total machine realignments have not been performed according to our accelerator’s scientists guideline. Underground and building settlement, thermal drifts or new beamlines installations can be the cause of some of these long-term drifts. Facing the future challenging ALBA II project, which purposes to convert ALBA Synchrotron from 3rd to 4th generation, through the partial replacement of the accelerator and new beamlines construction, a global view on the facility steadiness along its first life period has been considered. The machine complex alignment drift can be analyzed by means of the historic collected data from the reference networks in the linac, tunnel and experimental area and correlated with some other interesting data like the radio frequency cavities frequency evolution.
