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/sup +/ through single UV photon absorption. For the plasma wake field acceleration experiment, the plasma density n/sub pe//spl ap/2-4/spl times/10/sup 14/ cm/sup -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.
