    Abstract: An electron generating device extracts electrons, through an electron sheath, from plasma produced using RF fields. The electron sheath is located near a grounded ring at one end of a negatively biased conducting surface, which is normally a cylinder. Extracted electrons pass through the grounded ring in the presence of a steady state axial magnetic field. Sufficiently large magnetic fields and/or RF power into the plasma allow for helicon plasma generation. The ion loss area is sufficiently large compared to the electron loss area to allow for total non-ambipolar extraction of all electrons leaving the plasma. Voids in the negatively-biased conducting surface allow the time-varying magnetic fields provided by the antenna to inductively couple to the plasma within the conducting surface. The conducting surface acts as a Faraday shield, which reduces any time-varying electric fields from entering the conductive surface, i.e. blocks capacitive coupling between the antenna and the plasma.

    Abstract: An electron flood apparatus 1 of the present invention comprises a chamber 22 having a first part 22a made of conductive material and a second part 22b made of insulating material, and extending along a predefined closed curve Ax. A coil 18 is provided outside the first part 22a to generate a magnetic field in a direction intersecting with the surface formed by the predefined closed curve Ax. The coil 18 and the chamber 22 are inductively coupled by the magnetic field. Since the inert gas plasma is generated in the chamber 22 mainly by inductive coupling, electrons contained in the plasma have a low energy. Here, by applying voltage to an electrode 21, electrons having a low energy in the chamber 22 are emitted from an opening 14.
