MBE Product: RHEED Gun, RHEED Oscillations, VIDEO-RHEED

High Performance RHEED Electron Gun HP-4


HP-4 is designed to deliver a very high quality beam under realistic MBE conditions. This is achieved by several beam alignments that can be adjusted while the gun is operating.

The position of the electron beam source can be varied to center the brightest spot of the filament on the optical axis. The first set of deflection plates then eliminates any deviation of the beam direction. And finally, the aperture manipulator allows the exact alignment of the electron beam with the axis of the magnetic lens for minimum aberrations.
