Dc breakdown of helium in the range to the left of the Paschen minimum is examined. An expression relating breakdown voltage to the pd product (pressure × inter-electrode distance) and the breakdown temperature of the free electron gas Maxwell spectrum is derived. The type of breakdown mechanism is deduced by submitting the measured values of breakdown voltage in the range to the left of the minimum...
A free-electrons' gas spectrum shape in gases under the influence of the electrical field is considered in the theoretical part of the paper. Based on the nature of electrons' interaction with ions and molecules (or atoms) of gas, it was concluded that the spectrum is Maxwellian, if noble gases and subpressures are used. This conclusion was experimentally verified in the Townsend's region of electrical...
