Injection from the K500 Superconducting Cyclotron into the 88" Cyclotron at Texas A&M

The construction of a superconducting cyclotron of the MSU design (K=500, Kf=160) is under way at Texas A&M. It will be used both alone and as an injector for the existing 88" (K147) cyclotron. A beam optics study has been carried out for injection of K500 cyclotron heavy-ion beams into the K147 cyclotron. This study traces a variety of beams from extraction at the K500 cyclotron until focused and dispersion matched into the proper orbit of the K147 cyclotron. The line is configured to decouple the parameters of each cyclotron by first bringing the momentum dispersion to zero and then producing a double waist which serves as the apparent source for the second cyclotron. Beam line optics for standalone operation of the K500 cyclotron, which provides for use of the present experimental facilities, have also been studied. Construction of the K500 cyclotron is proceeding approximately on schedule with operation expected in 1985.
