which use to adjust electron cathode and rf circuits concentricity for high frequency millimeter wave applications.These rf circuits
with diameter 0.2mm
must be aligned from the cathode to the collector.A laser alignment system can measure and adjust the concentricity from cathode to rf circuits.The laser beam through the pinhole in the cathode and the rf circuits was received by a photodetector in the collector area.This technique is simple and can adjust the concentricity very well.
