Abstract (en)

[origin: EP0827179A1] A single potential ion source 50 includes a single conical electrode 58 encircled by a cylindrical magnet 60. At least one filament 56 is placed proximate to the electrode. This arrangement serves to accelerate electrons created by energy from the filament toward a centre axis 59 of the conical electrode. The electrons collide with gas particles to create a focussed ion stream. The stream may be directed into a magnetic field in a mass spectrometer tube. A base 52 supports pins 54 for electrical connections to the electrode 58 and filaments 56. <IMAGE>
