Amplitude Technologies works to provide solutions for the future and today proposes a PetaWatt laser system working at 1 Hz for proton therapy and fundamental physics.
The laser system:
The PW laser architecture which is proposed by Amplitude Technologies is the one designed for the SAPHIR project, e.g. prepared for repetition rates up to 5 Hz. Pump lasers TITAN of the PW amplifier have 5 Hz repetition rates capability while keeping the same performances.
PetaWatt configurations include the latest development from Amplitude R & D to achieve high peak power system with unique performances;
The application: Particle acceleration for proton therapy
With more than 55 000 patients treated in the world, proton therapy has proven its efficiency. It constitutes an excellent treatment in certain cancers today.
However, the implementation of this technique requires a heavy and expensive infrastructure around particle accelerators, which today constitutes as a major limitation in its development. While the need is estimated at more than 500 centers in the world, today only around thirty are in service. With an ultra-intense laser like the PW, the ephemerally created electric field would allow to accelerate protons until 150 MeV for heavy particles and GeV for electrons. These energetic particles may be used for medical applications, especially in Oncology.
If this approach is resolved in a reproducible way, we can envisage the manufacturing of useful machines of a suitable size and at a reduced cost, at least with regard to the current devices.
