ABSTRACT:
Object
To improve detecting sensitivity of negative ions.
Construction
A mass-filtered negative ion beam 22 is irradiated on a plate 24 after passing through a slit to emit neutral atoms 27, the neutral atoms 27 being ionized by an electron flow 33 after passing through a mesh electrode 30, the ion beam 35 ionized entering to a secondary electron multiplier to be amplified, then the amplified current entering to an amplifier 37 to be further amplified.
Effects
The detecting sensitivity can be improved more than ten times owing to the difference in existing amount of sputtering yield between neutral atoms and secondary ions.
