## Definition

the trail of energy left behind by a group of moving particles. Other particles can follow this trail to gain speed, much like a surfer riding a wave.

For teachers: the electromagnetic field left behind by a bunch of charged particles as they travel through a medium or structure. This field can accelerate trailing particles, a phenomenon exploited in advanced particle accelerator designs.

## Examples

- The electrons gain energy by riding the wakefield.
- Scientists are researching wakefield acceleration to create smaller, more powerful particle accelerators for medical and industrial use.
- By precisely timing the injection of a witness bunch into the wakefield of a driver beam, researchers can achieve significantly higher acceleration gradients than traditional methods allow.

## Usage notes

- Commonly used in the context of plasma physics and particle acceleration; often appears in the compound 'wakefield acceleration'.
