The Rhodotron® is a recirculating accelerator where electrons gain energy by crossing a coaxial-shaped accelerating cavity several times. This original design makes it possible to operate the machine in continuous mode for maximum efficiency and throughput
Advantages |
Highest beam current accuracy |
The Rhodotron® offers the highest beam current accuracy at both high and low current ratings. This allows very precise dose deposition.
Tightest energy spectrum |
energy level stability is built into the Rhodotron® design. The Rhodotron®’s extremely tight energy spectrum allows great flexibility and control in beam line and scanning optics. Furthermore even at very low and very high power, the voltage remains stable, ensuring unchanged dose deposition.
|
|
|
Non diverging beam output |
The Rhodotron® can be supplied with a two-staged scan horn system that delivers a non-diverging (parallel ray) beam. This unique Rhodotron® option provides both the uniformity of dose delivery and the efficiency of beam utilization. |
|
 |
Electrical efficiency |
the Rhodotron® has "wall-plug to beam power" electrical efficiencies of up to 50 percent depending upon the beam power and model, and is consistently 2 to 4 times more efficient than competing units.
These efficiencies translate into savings of hundreds of thousands of dollars per year, depending upon the size of the unit and local electricity rates. |
|
 |
 |
|
Versatility |
Since it offers the full power range and multiple beam lines rated at different energies can be extracted from a single electron accelerator, you can configure a single Rhodotron® to drive an entire multi-purpose sterilization / cross-linking facility. |
Fastest ramps |
The power of the Rhodotron® instantly adapts to line speed while maintaining a constant dose even at very low current. Production throughput is therefore dictated by your requirements rather than constrained by the irradiation system’s capacity.
Similarly, the start-up time of the Rhodotron is very short, allowing for no warm-up process.
Highest Capacity |
systems all the way up to 700 kW are available from IBA.

Operation highights |
1 - Electrons are fired by the heated filament of the electron source located at the outer wall of the cavity (1).
2 - The electrons are introduced into the cavity when the electric field is such that it will accelerate the electrons inwards, towards the hollow coaxial cylinder in the center.
3 - The electrons pass through openings in the inner cylinder while the electric field is reversing
4 - On emerging from the inner cylinder, the electrons are further accelerated (towards the outer cavity wall) under the influence of the new reversed field.
|
|
|
5 - Using beam deflection magnets, the electrons are reintroduced into the main
body of the accelerator for additional crossings of the cavity in order to reach
the required energy level and leave the cavity through a beam line ( 6 ). |
