Abstract :
A lithium (Li) plasma source is described that can be used for plasma acceleration as well as for electron beam focusing (plasma lens). The Li vapor with a density in the range is produced in a heat-pipe oven. The Li is ionized to Li+ through single UV photon absorption. For the plasma wake field acceleration experiment, the plasma density npe≈2-4×1014 cm-3 is 1-meter long plasma. A shorter length of uniform plasma density can be used as an underdense plasma lens, or the plasma density can be tapered for an underdense tapered plasma lens
