Introduction

The system refers to a high voltage generator made by modular structures connected in series. Each module is wireless powered by photovoltaic cells illuminated by a laser system. Also each module is equipped with a control and monitoring board allowing excellent stability.

High voltage is used as electrical potential to accelerate protons provided by an ion source.

Technical features

The high voltage is generated via a new technique: the potential of each electrode is achieved by discs connected in series that work as voltage generators: stabilized, optically powered, and electrically floating. The power is fed with lasers on optical fibers, converted into electrical power by photovoltaic cells.

Thus, the accelerator is modular and scalable; features not available in the current devices. The electrical insulation is provided by a dielectric liquid. This allows a more economic, compact and easily maintainable product. Moreover, the voltage generators are independently stabilized. The use of a fluid avoids high pressure gases.

Possible Applications

• Ion implantation;
• X-Ray production for radiotherapy;
• Radiation-Hard testing;
• Material analysis (PIXE);
• Every activity nowadays done with small particle accelerators.

Advantages

• Modularity;
• Scalability;
• Stability;
• Absence of high pressure gas;
• Ease of maintenance.
