A beam tracking optical table for synchrotron X-ray beamlines

A platform for experiments at synchrotron radiation sources which automatically adjusts its position to compensate for beam drift has been designed. The platform consists of an optical table top that is placed on a motorised support. Fixed rigidly to the table top is the incident beam collimator. Two monitors in front of the apertures of the collimator measure the beam position with high precision. The beam position is continually assessed by software and if any beam displacement is detected, the position of the optical table is adjusted to re-establish alignment.
