Notes:
A beam diode was operated successfully at a pressure as high as 10−1–10−2 Torr of gases (He, H2, Ne, N2, CO2, and SF6). Each gas had its optimum pressure pm at which electron beam currents were higher in peak values than those for conventional in-vacuum operation by a factor of 1.5 or more. A relationship pm×σ1.18H =const. was obtained where σH is the total ionization cross section in gases at some hundred keV. A model was proposed for such operations, and those high-pressure operations are preferable to the conventional if one needs higher currents.
