What is E-beam Technology?
Electron Beam (E-Beam) technology is a process where a stream of high-energy electrons is accelerated and directed onto a target material. These electrons carry kinetic energy that penetrates matter and causes molecular-level changes — such as crosslinking, chain scission, sterilization, or color transformation.
It is a clean, green, and highly controllable technology with applications across diamonds, cables, polymers, medical devices, and food.
How It Works at Cromwell eBeam Solutions
At Cromwell eBeam Solutions, we operate a 3 MeV, 100 kW industrial electron beam
accelerator from NHV Corporation, Japan.
1. Electron Generation → Electrons are emitted from a heated tungsten filament(cathode).
2. Acceleration → These electrons are accelerated to 3 million electron volts (MeV) using a linear accelerator.
3. Beam Formation → The high-energy electron beam is scanned into a controlled curtain-like shape using magnetic deflection.
4. Material Exposure → Products (diamonds, cables, polymers) pass under the beam on conveyor systems or drum handling systems.
5. Molecular Interaction →
○In polymers: causes crosslinking (strengthening, heat resistance) or chainscission (controlled degradation).
○In diamonds: displaces atoms in the crystal lattice, leading to color centers
that produce fancy diamond colors.
○ In sterilization/food: breaks down DNA of microorganisms, ensuring safety
without chemicals.
