Sodium atoms (10/sup 8/--10/sup 11/ cm/sup -3/) effused from an oven where excited by two pulsed dye lasers (--8--15 ns, --100 ..mu..J) from the ground state 3s, via an intermediate state 3p, to a Rydberg state ns or nd (20less than or equal tonless than or equal to25). About 50 ns after the laser irradiation, a pulsed electric field (0.5--5.5 kV/cm) was applied to the Rydberg atoms to ionize them and accelerate the resulting ions. Thus, a pulsed ion beam was obtained with a maximum total electric charge of --5 pC, corresponding to a peak current of --25 ..mu..A with an output pulse of --200 ns full width at half-maximum.
