Abstract: A Hydrostatic Levelling System (HLS) has been installed at Diamond Light Source. 8 sensors have been positioned along a 60 metre portion of the floor of the Storage Ring and the Experimental Hall, stretching out along a typical beamline route from Insertion Device to sample. 7 of the sensors are installed on the thick, reinforced concrete floor of the Experimental Hall which is supported on piles and the last sensor is mounted on the much thinner concrete floor of the peripheral walkway which has no piles. The foundations and floor were designed to achieve settlements measuring 1 micron per 10 metres per hour and 10 microns per 10 metres per day. A larger range was specified of 250 microns per 10 metres per year on the Experimental Hall floor and 100 microns per 10 metres per year in the Storage Ring to account for longer term settlement effects and seasonal variation and the HLS has been installed to try and measure these very small movements. Results after one year of operation are presented.
