The gaseous breakdown conditions by the microwave field were theoretically and experimentally investigated in the presence of an external crossed magnetic field. We developed the calculating method by taking account of collisions between electrons and neutral gases, and electron losses to a boundary in the magnetic field to be able to calculate the breakdown voltages in a low gas pressure range from 1×10^-4 to 1×10^-2Torr. These calculated results are in good agreement with experimental ones. In the narrow-gap less than the wavelength of the microwave, both the magnetic field and the electron loss to the boundary play an important role for the breakdown condition. Coaxial-type electron cyclotron resonance (ECR) plasmas can be generated in a metal coaxial tube with a gap length of 4.5mm gap.
