Title: Charged particle energy analyzer
Inventor: YAMAUCHI HIROSHI
IPC: G01N23/225
Filed: 1983-11-07
Abstract: PURPOSE:To make it possible to analyze plural energies at the same time by providing plural low-pass filters on one side of an elliptical surface of revolution and also plural high-pass filters on the other side, being arranged to oppose to each other. CONSTITUTION:When a sample 8 is excited by an X-ray source 12, the sample 8 emits electrons in all directions. Since a low-pass filter FL and reflector M are each set at the prescribed eletric potential, electrons with kinetic energy overcoming this potential hit against the reflector M and are absorbed there, while electrons with kinetic energy lower than this potential are reflected by the reflector M. The reflected electrons, after being focused at the center point F2 in a slit 6, move toward a high-pass filter FH, and those electrons with kinetic energy overcoming the set electric potential pass through an electric grid 5. When the low-pass filter FL and the high-pass filter FH, which are opposed to each other, are each set in advance at an electric potential in accordance with the energy to be analyzed, plural energies can be analyzed at the same time without scanning an applied voltage.

Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal discharge in a film forming stage by allowing an atmospheric gas to flow from the upper part to the lower part. SOLUTION: An atmospheric gas feed tube 3 of a carbon target 1 in which the faces are vertically arranged is provided along the upper end of a chimney 5 surrounding the target 1, and an atmospheric gas of argon or the like is allowed to flow from the upper direction to the lower direction along the sheet faces of the target 1.
