【 摘 要 】

Improvements in the Fermilab operating 400-MeV linear accelerator injector are required to achieve the beam intensity and emittance requirement of the Proton Driver design study (5). It has been determined that these requirements can be achieved by replacing the components in the Linac below 10 MeV. An improved H(sup (minus)) ion source with an electrostatic transport to a two-section Radio-Frequency Quadrupole (RFQ) accelerator, with the RFQ sections separated by a magnetic five-dimensional phase-space imaging system as used in an earlier Fermilab/SAIC PET Project, and a new 10-MeV drift-tube linac cavity have been studied. It appears possible that an H(sup (minus)) intensity of 4.5 x 10(sup 13) ions per pulse with an improvement in beam emittance from the present system can be achieved with the proposed changes.
