Acceleration test of heavy-ion in RFQ linac for HIF basic experiments

A new heavy-ion acceleration system has been developed for basic research o n heavy-ion inertial fusion and ion-pumped laser at Tokyo Institute of Tech nology. This system consists of the TIT-RFQ linac, a hexapole cusp-field ty pe ion source, a solenoid lens, magnetic quadrupole lenses and an analyzing magnet. By using the new system, acceleration of Nf beam by the TIT-RFQ wa s first possible. We could obtain N+ beam with an energy of 3.066 MeV and a maximum intensity of 0.4 nA as the results of acceleration test. The outli ne of this system and the acceleration test are presented.
