valve (control it by watching the
marker of the valve plug which is
directed forwards to the observer
when the valve is open, see blue
arrow in figure on the left).
9. Take the dummy push rod for the
alignment procedure. While the
original push rod is already in the
vertical position, insert the dummy
into the valve as far as possible. If
this is consistent with the position
in the figure left, positioning of the
push rod in the ion source is correct
and you can skip the steps 11 - 12.

of the brass block slightly. Now you
can cautiously move the valve block
