We report here on the first measurements of decay times, during the beam pulse, of plasmas generated by intense relativistic electron beams. The pressure scaling of characteristic decay times and detailed temporal evolution are consistent with a simple plasma-electron generation model which includes direct-impact ionization, avalanche, and recombination. The decay times have been correlated with observed frequencies of the beam resistive hose instability, and the inverse relationship between ..omega.. and tau predicted by linear theory has been experimentally verified.
