Single potential ion source |
摘要 |
A single potential ion source includes a single conical electrode encircled by a cylindrical magnet. At least one filament is placed proximate to the electrode. This arrangement serves to accelerate electrons created by energy from the filament toward a center axis of the conical electrode. The electrons collide with gas particles to create a focused ion stream. The stream may be directed into a magnetic field in a mass spectrometer tube.
