1numbers in parentheses indicate an estimated charge exchange efficiency
2Beam on target estimated to be 10% of that into the tandem for A<100 and 5% for A>100 assuming single stripping in the tandem. Double stripping reduces the beam intensity by a factor of 10 but should permit a more favorable initial charge state to be used.
