摘要：

A technique has been developed to evaluate ionization and attachment coefficients for electrons traveling in gases across a uniform electric field by measuring the integrated-anode-current/time profile for a pulse of electrons released from the cathode. The main advantage of the method is that the time-resolved technique clearly distinguishes the current due to delayed effects, such as the arrival of negative ions in attaching gases or electrons produced by the metastable collisional ionization of trace gases present in the inert gases. The method has been adopted to determine ionization coefficients in hydrogen, nitrogen and helium, and both ionization and attachment coefficients in oxygen and carbon tetrafluoride.
