Hydrostatic Level System (HLS)
This system will give the physicists a better idea of how the magnet positions drift from day-to-day. The system consists of a series of cans connected by a pipe. The pipe and cans are half full of water. Each can contains a sensor to measure the water depth to a few microns. If the vertical position of a magnet changes, the measured water depth will also change. Data from the HLS combined with the tilt-meters already installed in the TeV will give the experts more things to point a finger at when the beam orbit needs correction.
