9.4.3 Assembly of Crystal-Multiplier Combination
Warning!
Multiplier may get damaged!
During servicing, the multiplier must not be exposed to bright
light.
Do not bolt together Mu-metal and coupling ring too hard, as this
may destroy the multiplier.
Tighten parts only until you encounter a slight resistance.
1
Before assembling the crystal-multiplier combination, clean the
optical contact area

with a soft cloth to remove remaining
silicon oil residues. The same is true for the crystal.

Attach crystal.
Gently push the crystal with a slightly rubbing motion against
the multiplier to distribute the drop of silicon oil and to estab-
lish a good optical connection.

Push the Mu metal screen over the multiplier and fix the com-
bination again to the coupling ring with screws.
