E-Beam Control Electronics
Our E-Beam Temperature Controller provides precise, reliable closed-loop control for electron-beam heating systems in ultra-high vacuum (UHV) environments. Designed specifically for use with McAllister electron-beam heater assemblies, this unit delivers focused, high-temperature heating through controlled electron emission, achieving superior performance where conventional resistive heating falls short.
The system features a robust control panel with dedicated controls for filament voltage (AC resistive heating of the tantalum filament) and high-voltage bias (0–1000 V DC for electron acceleration). It supports emission currents up to approximately 125 mA, enabling rapid, localized heating of the sample plate while minimizing thermal impact on surrounding components. Integrated with a Watlow temperature controller, it offers programmable ramp rates (e.g., 20°C/min), PID-based closed-loop operation, and manual override modes for flexibility across research and process applications.
Key features include:
- Safe, interlocked high-voltage operation with clear indicators for power, HV status, and emission monitoring (selectable mA/V display).
- Precise filament control via adjustable voltage and real-time current metering.
- Thermocouple integration for accurate sample temperature feedback and control.
- Compact, laboratory-ready design engineered for indoor use with specified cabling and grounded vacuum systems.
This controller is the ideal companion for McAllister UHV manipulators and sample holders, delivering the high temperatures and focused energy delivery essential for surface science, thin-film deposition, and materials analysis. Built for years of dependable service in demanding vacuum environments.
