Pearson Electronics designs and manufactures custom Current Monitors for use in the beam tube, and large aperture clamp-on Current Monitors applied outside the beam tube. Pearson Current Monitors measure sub-milliamp currents. Pulse rise times as fast as 1.5 nanoseconds can be viewed accurately.
Pearson Wide-band Current Monitors can be hardened against neutron radiation by eliminating the use of Teflon. A Vacuum level of 2E-7 torr with 12 L/sec effective pumping speed and an outgas rate ~2.4 torr L/sec has been obtained with our in-stock off the shelf models.
