Beam Diagnostic

Beam 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.

Low 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.

Faraday Cups

NEC manufactures several types of Faraday cups designed for accurate measurement of ion beam currents.
