The Argonne Wakefield Accelerator is an accelerator currently in development that uses constructive interference to increase power. The theory behind it can be equated to a boat's acceleration when it rides in another boat's wake, except the boats are electrons and the waves are electromagnetic waves.
Various components used in the accelerator. The quadrupole looks very familiar to some of us (Emma and Elianna) after our instrumental class last semester. The last little tube is what makes this accelerator so special.
Here you can see the the drive beam which acts as the "first boat" and produces the initial EM waves that a second beam, the witness beam, can ride on. If everything works correctly the witness beam will be accelerated. This technology could greatly reduce the length of beamlines and therefore reduce some of the current barriers in accelerator physics.
