Zusammenfassung:A substrate penetrates a main seal in an ionization chamber filled with pressurized gas. In one form of the present invention, a second chamber is provided around the region of penetration. The substrate then also penetrates the second chamber. The second chamber is pressurized with a gas at a lower pressure than in the ionization chamber. Thus, the pressure differential across the main seal is lowered, thereby reducing the load on the main seal.
