Since then, the LIS has provided many heavy ion species successfully. The induced low charge state (mostly singly charged) beams are injected to the Electron Beam Ion Source (EBIS) where ions are then highly ionized to fit to the following accelerator's Q/M acceptance, like Au³²⁺. Last year, we upgraded the LIS to be able to provide two different beams into EBIS on a pulse-to- pulse basis.

	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.

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.
