AdA – the world’s first electron–positron storage ring

The story of the world’s first electron–positron storage ring, the Anello di Accumulazione (AdA), starts in the hills above Rome. In a small city named Frascati. It is famous for many things, but first above by its beautiful view on Rome.

AdA was built in Italian National Institute of Nuclear Physics (INFN), under the leadership of Bruno Touschek, it stored its first beams in February 1961. A year later it was transported to France, to a small city in the neighborhood of Paris named Orsay.
