Descrizione
The generation of high-power, ultrashort pulsed electron beams is a key characteristic of
modern radiotherapy techniques based on the FLASH effect.
One of the most promising techniques in this field is Laser-Linacs (LL), which is based on the
Laser Wakefield Acceleration (LWFA) process. In this process, a high-power, ultra-short laser
pulse is focused into a gas-jet target to generate a plasma wave that can accelerate electrons
injected into the plasma at the correct phase.
Recent studies and simulations have shown that using a gas jet target with a structured
chemical gradient can improve control over the depth of electron injection into the plasma
and improve the energy spectrum of the resulting electron beam.
In this context, the JET-LEA (JEt Target for Laser Electron Acceleration) project was started with
the objective of designing and characterising a continuous recirculating gas jet target.
The JET-LEA project and its main results will be presented during the workshop.
