Title: High speed atomic beam source
Inventor: NAGAI KAZUTOSHI
IPC: H05H3/02
Filed: 1988-12-19
Abstract: PURPOSE:To enable the easy generation of a large quantity of high speed atomic beams by providing a constitution capable of applying a magnetic field vertically crossing to the electric field between an anode and a cathode and regulating a discharge voltage and an ion accelerating voltage independently. CONSTITUTION:When the circumference of a disc form cathode 22 has a knife edge, a large quantity of ions is formed at a low discharge voltage because of the access of the knife edge to the inner wall of an anode 21 and the application of a magnetic field 24 parallel to the cylinder shaft of the anode 21.

When annealing is performed, the variable resistor 4 is set at a specified value, and a switch 5 is turned ON to close, a circuit connecting the electrodes 3 and 3 and the power source 6. A current flows through the wound core 1 for which the voltage is applied across the electrodes 3 and 3 in the axial direction. Therefore, Joule heat is generated owing to the resistance in the wound core 1. Thus the temperature of the core is increased. Therefore, Joule heat is uniformly generated at various parts of the wound core 1, and the temperature distribution in the wound core becomes uniform.
