Disassembling the Source
Open Source
•
Remove the filament (see instructions in this chapter).
•
Loosen the set screws on the barrel connectors that hold the three leads
coming down from the source elements. The repeller, source and focus
plate can now easily be removed.
Assembly and Installation
Refer to Figure 6-3.
1.
Install the focus element first so that its long wire engages the correct
barrel connector at #1 (Figure 6-1). The back surface of the focus plate
should rest against the ceramic collar of the mass filter. Tighten the bar-
rel connector set screw snugly but do not overtighten.
2.
Install the source so that its plate is spaced about 0.1” above the focus
plate with its long wire in the correct barrel connector at #10 (Figure
6-1). Tighten the connection.
3.
Install the repeller so that its plate is spaced about 0.1” above the source
grid with its long wire in the correct barrel connector #2 (Figure 6-1).
Tighten the connection.
4.
Install the filament as described earlier in this chapter.
5.
Insert the head into the vacuum chamber and secure using the six bolts
originally removed. Tighten the bolts using a cross pattern to ensure
proper tightening and a leak-tight connection. The maximum torque
required is 110 in-lb (9 ft-lb).
6.
Check for electrical isolation between the feedthrough pins.
