Riber HEED 510 Alimentation Optique Optical Power Unit 220V 0.5A HEED MBE

Riber HEED 510 Alimentation Optique Optical Power Unit 220V 0.5A HEED MBE

The Riber HEED 510 is a specialized optical power and electron beam control unit designed for use with Riber HEED (High Energy Electron Diffraction) systems in MBE (Molecular Beam Epitaxy) and thin-film research environments. Built by ISA Riber in France and dating from the early 1990s, this unit provides stabilized power and precise deflection control for HEED/RHEED electron gun assemblies. It integrates a dedicated focusing power supply module and a multi-axis deflection and alignment control section on a single rackmount/benchtop chassis.

Applications

The Riber HEED 510 is a purpose-built power and control unit for HEED and RHEED (Reflection High Energy Electron Diffraction) systems, which are standard in-situ surface analysis tools used during MBE (Molecular Beam Epitaxy) thin-film growth. In an MBE system, a RHEED gun directs a grazing-incidence electron beam at the sample surface; the diffraction pattern on a phosphor screen provides real-time information about surface structure and film quality during growth. The HEED 510 provides the deflection plate voltages, focusing coil current, and alignment controls needed to aim and shape that electron beam precisely. Riber was a leading French manufacturer of MBE systems and associated analytical equipment from the 1970s through the 1990s, and their HEED/RHEED power units are found in university research labs, national laboratories, and semiconductor R&D facilities that maintain Riber MBE systems. Replacement or spare HEED power units for Riber MBE systems are uncommon on the used market, making this a relevant find for groups maintaining legacy Riber equipment.
