  The Spallation Neutron Source (SNS) uses a laserwire to measure the transverse profiles in the Super Conduction Linac (SCL). The laser is located in a service building downstream from the SCL. Mirrors direct the laser light to a specific location to interact with the ion beam. Because of the long travel length of the light, up to 300 feet, minor mirror movements become large enough at the down stream station that the drift over time must be corrected. In this paper we describe how we correct for the drift and present our results.
