PLasma based ION Acceleration (PLIONA)

Laser-driven plasma-based accelerators can sustain acceleration gradients that are many orders of magnitude larger than those achievable in conventional accelerators. The acceleration distance can thus be reduced correspondingly, and plasma-based accelerators can be made extremely compact. The aim of this project is to contribute to the development of laser-plasma based ion sources. The main objective is to increase the efficiency, energy and beam quality of these sources.

The ion beams produced in laser-plasma accelerators have some very attractive properties, e.g. ultra-short duration at the source, large particle number and high degree of laminarity (low transverse emittance). They could potentially be suitable for a wide range of novel applications, such as hadron therapy, study of cosmic radiation damage to living organisms and spacecraft components (in particular solar cells), production of short-lived isotopes for medical diagnostics with positron emission tomography, proton imaging, injectors for conventional accelerators, thin layer activation for obtaining information about the wear or corrosion of machine parts etc.

The Knut and Alice Wallenberg foundation awarded 38.5MSEK for a 5-year project (1 July 2014 -- 30 Jun 2019) on the above topic (the PLIONA project). Short popular science film on the project can be seen on the webpage of the Wallenberg foundation.
