Experiments with short-lived Ra nuclides require high intensity heavy ion beams such as 206Pb at 8.5 MeV/amu. During acceleration charge exchange with rest gas occurs. Charge exchanged particles eventually hit the walls of the cyclotron, leading to desorption, which in turn gives rise to vacuum degradation. This positive feedback process leads to a deterioration of the transmission, limiting...
