AWAKE – Plasma Wakefield Acceleration

The AWAKE (Advanced Proton Driven Plasma Wakefield Acceleration Experiment) group at the MPP is investigating a new method to accelerate particles to high energies. The method involves injecting a proton beam into a plasma, i.e. an ionized gas. En route, the protons entrain negatively charged plasma electrons and thus generate a kind of bow wave. If a beam of electrons is injected at a suitable point in time, they are carried along by the wave – just like a surfer riding a wave.

The research seeks to reduce the distance that is required to accelerate particles. The technique is particularly suitable for linear accelerators – and is a lower-cost alternative to the concepts proposed for the International Linear Collider (ILC) or the CERN Compact Linear Collider (CLIC).

Current research

The MPP is currently collaborating with international partners to set up the AWAKE experiment at CERN in order to achieve this objective. The Group is investigating methods that will allow the energy of the proton sources currently available – the LHC, for example – to be used for AWAKE. The aim is for the proton beam to generate charged waves in a plasma over a distance of 10 to 1,000 meters. This will allow electron beams to be accelerated up to the teraelectronvolt energy range (TeV, one million gigaelectronvolts).

A plasma accelerator would then need only 85 centimeters to accelerate electrons to an energy of 50 gigaelectronvolts. The SLAC particle accelerator, an experiment currently underway, needs 3 kilometers for this.

The innovative AWAKE technology is based on a plasma wave on which electrons "surf" and are accelerated to collide with other particles. A study has now shown how the surf waves can be precisely controlled – an essential prerequisite for AWAKE to one day be used for particle physics experiments. The…
