 note = {application/pdf, A discharge apparatus for measurement of the Townsend first ionization coefficient α in various gases by the steady-state Townsend method has been produced. The purpose of this paper is to confirm the accuracy and reliability of the apparatus by measuring the α values in hydrogen. The reason for using hydrogen is that there is little difference between its α values for each investigator compared with other gases and the gas is frequently employed as a suitable one for testing such an apparatus. The results show that the α values obtained over the E/P_0 range 40＜E/ P_0＜200 Vcm^<-I> Torr^<-l> are in excellent agreement with earlier ones. It is also found that the α values are unchanged for ten hours after enclosing the gas, provided that hydrogen with purity of 99.9％ is used, as in the present study.},
