2	2	the resultant Hydrogen molecules occur. After the quadrupole lens cleans out the charged particles from the stream only neutral H atoms and H,,2,, molecules remain (Actually the quadrupole can pass protons created when atoms strip close to the electrodes, so a
3	3	Cleaner electrode 12.8 cm downstream of the quad removes them from the stream). At this point the
4		~100 molecules/sec of H,,2,, must be removed from the 10~~^^ 11~~ ^^ atoms/sec of H. To do this we use a gas cell to strip a portion of this stream so that afterwards the charged particles can be seperated by an electrostatic energy analyzer.
