title: Direct plasma injection scheme in accelerators.
abstract: The idea of direct plasma injection scheme (DPIS) was proposed in 2000. This new technique has been studied and proven to accelerate intense ion beams. To provide medium mass ions with highly charged states, small tabletop solid lasers were used for plasma production. Based on the measured plasma properties, aluminum and carbon ions were accelerated with more than 60 mA of current. The next experiments will use an radio frequency quadrupole designed for q/m=1/6 and explore beam productions using targets up to silver, and future work will explore production up to uranium. The DPIS has been established and is ready to be used with various accelerators which require pulsed high current, high charge state ion beams.
