The purpose of the 5 MeV test beam project is to generate a quasi-DC electron beam which can be use to simulate the electron cooling system envisioned for the Recycler ring. It would allow tests of latice designs, magnet prototypes, and beam diagnostic concepts well in advance of commissioning of the electron cooling system itself. .
