Abstract

The method involves generating a pre-vacuum with a vacuum pump (4), which is separated from the atmosphere by a first valve (5), for a high vacuum pump (3) connected to a first vacuum chamber. The vacuum pump also generates the vacuum in a second vacuum chamber (2). During the full operation of the high vacuum pump, the first valve is closed and a second valve to evacuate the second vacuum chamber is opened.
