6.17.1.8 Wait 25 minutes. If the
expansion chamber pressure
changes by 0.2 Torr or more
then there is a probably leak in
the connection to the bottle or
at the NPT to VCR adapter.
Tighten the VCR connection
slightly and see if that solves
the leak. If not, continue to
pump for another 5 minutes to
remove any XeF2 left in the
lines and close the valves.
Loosen the VCR connection to
the bottle and check the
tightness of the NPT to VCR
adapter in the bottle valve.
Replace the gasket at the bottle
VCR fitting and rerun the leak
test starting at Step 6.17.1.5.
6.17.1.9 If this procedure continues to
fail, remove the bottle and
install a VCR plug with a new
VCR gasket. Rerun the
procedure starting at Step
6.17.1.10 If Step 6.17.1.9 passes, remove
the NPT to VCR adapter,
remove any Teflon tape, re-
apply a fresh wrap of Teflon
tape, and re-install into the
system. Rerun the procedure
starting at Step 6.17.1.5 and
this should solve the problem.
If Step 6.17.1.9 does not pass,
it may be necessary to use a
helium leak detector to check
