Paper Abstract

In the first part of this paper, we describe our strategy about how to deal with the problem of maintaining the reflective surface and how we use a portable scatterometer/reflectometer to monitor our results. The second part of this paper will describe and present preliminary results from an experiment designed to determine the optimum procedure for cleaning a front-surface metal coated mirror that is exposed at this high-altitude site.
