Description
IVS FE Gun Control Accuvision 200 Rackmount Field Emission Gun Controller
The IVS FE Gun Control is a rackmount controller designed for the IVS Accuvision 200 field emission electron gun system. It provides centralized power switching, fault monitoring, and voltage/current metering for the major functions of an FE electron gun column — including the gun itself, the bake cycle, the sublimator, and main power. The front panel includes a 0–200 microampere DC analog extraction current meter and individual status indicators for all major fault and operational states.

Applications
Field emission (FE) gun control units like this IVS model serve as the central supervisory and power-distribution hub for field emission electron gun columns used in scanning electron microscopes (SEM), electron beam deposition systems, and related vacuum instrumentation. In an FE gun system, the controller manages the high-voltage supplies for the extractor, suppressor, and beam electrodes, while also sequencing the bake-out and sublimation cycles required to maintain the ultra-high vacuum environment around the tungsten or ZrO/W field emission tip. The Accuvision 200 platform was an IVS (Integrated Vacuum Systems) product line aimed at electron-beam and vacuum process applications, likely dating from the 1980s to early 1990s based on the construction style, panel layout, and connector types. This type of control unit is typically found in university research labs, national laboratories, semiconductor research facilities, and advanced materials characterization environments where electron beam sources are in regular use. Replacement and spare units for legacy FE gun systems are difficult to source, making this a valuable find for facilities maintaining Accuvision 200 or compatible IVS equipment.
This IVS FE Gun Control unit for the Accuvision 200 system has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The front panel, LEDs, switches, and meter appear intact and undamaged. The rear panel connectors — including the D-Sub logic, monitor, and program ports, the twist-lock sublimator output, and the high-voltage tip and suppressor connectors — show normal service wear. Attached cables are included as shown in the photos. Please view our photo set and contact us if you have any questions.
