Synchro-cyclotron

Some years ago, at the CERN Synchro-cyclotron, a CERN-Pisa Collaboration [1] devised an experimental scheme to perform a laser-induced transition experiment on a muonic helium ion (n 4He) At that time a rather complex set-up, intimately connected with the operation of the Synchro-cyclotron itself, was installed and made to work, and the energy level differences D = 2 - 2P (see Table 1) were measured with an accuracy of 1.5 x 10 4. In Table 1 are presented the experimental results as well as the expected... 

Finally there is the 184-inch synchro-cyclotron which was rebuilt in 1957 and now produces 720-mil-lion-volt particles. A great deal of work is now in progress and will go on for many years with this 4,000-ton machine.
