Riber JBA 12A Vacuum Pressure Gauge Controller Rackmount Sputtering PVD

Riber JBA 12A Vacuum Pressure Gauge Controller Rackmount Sputtering PVD

The Riber JBA 12A (also labeled "Alimentation de Jauge" — French for Gauge Power Supply/Controller) is a 2U rackmount vacuum pressure gauge controller designed by ISA Riber for use with ionization gauge tubes in high-vacuum and ultra-high-vacuum systems. It provides the regulated high-voltage supply and measurement readout needed to operate ionization gauges across a wide logarithmic pressure range, displaying chamber vacuum level on a front-panel analog meter.

Applications

The Riber JBA 12A is a vacuum gauge controller of the type used in physical vapor deposition (PVD) systems, including magnetron sputtering, thermal evaporation, and molecular beam epitaxy (MBE) chambers — all areas where Riber was a well-known French manufacturer. This class of instrument provides the high-voltage excitation current for hot-cathode or cold-cathode ionization gauge tubes and reads the resulting ion current as a calibrated pressure value, typically in the high-vacuum to ultra-high-vacuum range (roughly 10⁻⁴ to 10⁻¹¹ Torr). The analog logarithmic readout was standard on vacuum controllers of this era — the receipt date on the internal label (April 1983) places this unit firmly in the early-1980s generation of laboratory and industrial thin-film deposition equipment. Riber instruments like this were commonly found in semiconductor research labs, university physics departments, and industrial thin-film coating facilities. Today, collectors, repair technicians, and researchers maintaining legacy Riber MBE or sputtering systems are the primary buyers for this type of controller.
