Title: Secondaty electron signal processing device
Inventor: SHINADA HIROYUKI
IPC: H01J37/244
Filed: 1986-11-21
Abstract: PURPOSE:To obtain a secondary electron signal processing device, in which a sufficient magnetic contrast is available with high reproducibility and the strength of a magnetic field can be made quantitative from the strength of the contrast, by adding a signal operational processing system, in which a prescribed operation is performed, to two secondary electron detected outputs. CONSTITUTION:Signals of secondary electron detectors 4-a and 4-b are amplified by amplifiers 15a and 15b to become signals SA and SB, respectively, and ratios of them are made in a division circuit to form signals SA/SB and SB/SA. The one signal SB/SA is inverted in an inverter circuit 17, and the inverted signal is added to the other signal SA/SB in an adder 18. Thus, a signal Ms=SA/SB-SB/ SA is obtained. This signal is used for brightness modulation in a cathode-ray tube. Quantitativeness for the strength of a leakage magnetic field can be performed by this signal Ms.

IPC: H01J49/42
Filed: 1988-10-31
Abstract: PURPOSE:To perform measurement to suit the purpose easily by allowing a proton beam from an ion source to follow two loci consisting of an arc of circle when it comes into magnet, and thereby providing free selectivity for the energy measuring range. CONSTITUTION:Each protons having passed through two electrostatic deflectors 6, 7 draw a minor basic radius R2 in a magnet 2. The one proceeding straight will draw a major basic radius R1. In case overall measurement is conducted by the use of the locus with minor basic radius R2, the peaks of for ex. As and Ga are measured simultaneously. Because this overall measurement must be done in a short while, a collimeter slit 22 is prepared wide. Then the fine spectrum is measured only in the neighborhood of one element. Thereby the radius of the circular arc locus JK drawn when the proton emitted by the ion source has come into the magnetic field can be varied to a plurality of values.
