NEC has a number of ways to measure ion beam magnitude and profile. Models are based on beam power and physical mounting constraints.
Product InfoBeam Profile Monitor
NEC Beam Profile Monitors (BPMs) provide a continuous scope display of the shape and position of the beam cross section in both X and Y coordinates. They can monitor beams of electrons, ions, and energetic neutral particles.
Product InfoLow Current Beam Profile Monitor
The Low Current Beam Profile Monitor, Model BPM90-LC, can be used with both positive and negative ions, electrons, and neutral beams, like all NEC BPM models.
Product InfoFaraday Cups
NEC manufactures several types of Faraday cups designed for accurate measurement of ion beam currents.
