EMMA (Electron Machine with Many Applications) is a novel type of accelerator using a technique called non-scaling fixed field alternating gradient (NS-FFAG). This machine is part of ASTeC's programme of advanced accelerator science and technology research.
ALICE serves as the injector to EMMA. You can read more about EMMA on the ASTeC programmes page.
