Status of the HLS System

The experience gained so far on the Hydrostatic Levelling System shows that micrometric range accuracies are indeed achievable, creating the preconditions for the beam-based alignment mode of operation of the SLS storage ring. However, the long-term behaviour of the HLS system is characterised by significant drifts. The progress achieved so far in establishing the causes of such behaviour is briefly outlined.
