	Accelerator-driven compact neutron sources have been developed to conduct nondestructive inspection more conveniently and/or on the spot with lower cost than other neutron sources, such as spallation sources and nuclear reactors. In typical compact source, proton or deuteron are injected into Li or Be. To develop a higher flax source than conventional ones, we propose a source with 7Li beam generated by laser ion source using direct injection scheme (DPIS) into RFQ linac. Because of the higher velocity of center of mass than that in the case of proton beam injection, generated neutrons are more collimated. In addition, laser ion source with DPIS is expected to accelerate mA class fully ionized 7Li beam stably with simple setup, while it is difficult for conventional ion sources. The high collimation and high current are expected to lead to higher neutron flax. In this presentation, we present a design of RFQ linac optimized to accelerate such a high current beam with shorter distance.

A laser ion source (LIS) provides several types of singly charged ions into an electron beam ion source (EBIS) followed by linear accelerator injectors for the Relativistic Heavy Ion Collider (RHIC) and the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory. In the present set-up of the LIS, beam current shape varies with time drastically. It is expected that the present current shape is not optimal for the ion trap of the EBIS. However, there are no knobs to modify the shape flexibly. Therefore, as an upgrade of the LIS, we install a coil and a pulsed circuit* that generates a fast-rising pulsed magnetic field to tailor the beam current shape. In this presentation, the effect of the magnetic field on the beam profile from the LIS and the performance of the injectors, such as the transmission and the charge injected into an accelerator downstream, are described.
