154 B Manufacturing process <strong>of</strong> Rb Vapor Cell II<br />

(a) Leak tight seal: The described manufacturing procedure <strong>of</strong> vapor cell II proves to be successful<br />

and seals the vapor cell very efficiently.<br />

(b) Enlargement <strong>of</strong> the squared area <strong>of</strong> Fig. B.2(a): Applying only a thin film <strong>of</strong> glue is important.<br />

This prevents the glue from covering the narrow aperture.<br />

Fig. B.2: Scanning electron microscope pictures <strong>of</strong> vapor cell II: This test<br />

sample h<strong>as</strong> been cut along the symmetry axis and reveals a cross<br />

section <strong>of</strong> the glued front facet. The pictures have been taken by<br />

Arno Weick from the Institute <strong>of</strong> Applied Physics, Darmstadt.
