Abstract

PURPOSE:To make possible the common use for a sample cathode having a hollow portion and for a sample cathode of block shape by arranging the side of a projection, which is formed in the same direction as the hollow portion of a cathode, in contact with the side of a recess which is cut in the body of the cathode.
