Abstract | The drift velocity of electrons in pure hydrogen, in pure deuterium, and in mixtures thereof, has been observed at low pressures using the following pulse technique for these gases for the first time. Plane parallel electrodes of a known separation and immersed in the gas to be studied are connected in series with a resistor and a source of potential. Ultra-violet light from a spark of very short duration is allowed to fall on the cathode, and the resulting pulse of photoelectrons of correspondingly short duration traverses the gap between the electrodes to the anode, where it is collected. The associated current transient displayed on an oscilloscope gives the electron transit time. The electron drift velocity is determined directly from the above experimental parameters. Standard ultra-high vacuum techniques are employed to ensure high gas purity. The drift velocities obtained are in good agreement with the previously reported measurements of Bradbury and Nielsen and of Pack and Phelps for hydrogen and of Pack, Voshall and Phelps for deuterium. Data for mixtures of hydrogen and deuterium have not been published hitherto. |
