2.
Clean the anode cup.
Clean the anode cup by wiping with a clean dry tissue and dusting it with dry
nitrogen or clean compressed air. Clean all the loose sputtered material on the
inside surface and the face of the cup using an abrasive pad such as
Scotchbrite. Wipe clean with a dry tissue and dust with dry nitrogen or
compressed air.
3.
Clean any particles or whiskers off of the magnet assembly.
Use a lint-
free cloth and clean compressed air. If there are stubborn particles that are
difficult to remove, touch the surface with scotch tape to remove the particles.
4.
Remove the O-ring from the ion source, if necessary.
Squeeze and push up from both sides with thumb and index finger to remove
the O-ring from the ion source. Clean, apply vacuum grease (Krytox), and
replace. Apply vacuum grease to the curved Rulon bearing that captures the o-
ring. If this surface and the o-ring are not lubricated, then the beam alignment
will not move freely. Also apply vacuum grease to the curved surface of the
toggle stick, which mates with the drive screws in the gun knob. This helps
the toggle stick slide freely against the drive screws.
5.
Dust inside the gun housing and the inside face of the front polepiece.
Be sure the curved face on the inside of the gun housing that meets the o-ring
is clean. This face can be lubricated if desired.
To Reassemble the Gun:
1.
Insert the anode cup into the anode cup insulator (sliding fit).
2.
Insert the anode assembly into the magnet assembly (loose sliding fit).
3.
Carefully place the magnet assembly against the edge of the rear
polepiece.
Slowly lower the magnet assembly in place until the rear polepiece is within
the magnet shield. The parts will be concentric to one another.
4.
Slip the ion source into the gun housing.
Pay particular attention that the O-ring is not damaged in the process.
Carefully align the white reference dot at the back of the gun to the mating
groove machined into the outside diameter of the gun housing.
5.
Insert the screw into the molded connector assembly and tighten.
