The Non Scaling Fixed Field Alternating Gradient (NSFFAG) EMMA accelerator has a purely linear lattice, and the crossing of resonances during acceleration is therefore a key characteristic of the beam dynamics. An accurate measurement of the tune is essential for a full understanding of the machine behaviour. However, commonly used measurement techniques require the beam to perform a large number

EMMA (Electron Machine with Many Applications) is a prototype non-scaling electron FFAG hosted at Daresbury Laboratory [1,2]. NS-FFAGs related to EMMA have an unprecedented potential for medical accelerators for carbon and proton hadron therapy. They could also be used as the accelerator for a sub-critical reactor. We summarise the design and commissioning of both the injection and extraction lines for this machine.

The Electron Model for Many Applications FFAG (EMMA) has been the object of extensive beam dynamics simulations during its design and construction phases, using the ray-tracing code Zgoubi, which has been retained as the on-line simulation engine. On the other hand EMMA commissioning requires further advanced beam dynamics studies as well as on-line and off-line simulations. This contribution reports on some aspects of the studies so performed during the last months using Zgoubi.
