    11This is the last section of the experiment where the actual detection of
    2 the resultant diatomic Hydrogen molecules occur. Also the neutral H atom beam
    3 created by either photo-detachment via the laser, or by strippng off of gasses
    4 within the system.
     2the 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
     3Cleaner 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.
