5 kV to 30 kV RHEED Systems

15 kV RHEED Gun
30 kV RHEED GunPower supply and remote control

High performance electron-optics design

At the heart of this RHEED electron gun sits an electron-optical design developed for professional high resolution Cathode Ray Tubes. Internal magnetic dipole and quadrupol corrections of the electron beam guarantee best shape, Gaussian beam profile. An indirectly heated Mixed-Metal-Type cathode developed for space applications delivers steady current for many years (tested for 15 years continuous operation).
