ANALYSIS METHOD FOR ELASTIC ELECTRON REFLECTION SPECTRA Russian patent published in 1994 - IPC

FIELD: physical electronics. SUBSTANCE: primary electron flow with energy difference ΔE_d=0.2-0.6 eV shaped by electron gun is sent to isofocusing lens system, which functions to retard (accelerate) it K₁=1 to 100 times in energy at the same time focusing it onto analyzed target. Beam reflected from target is focused by means of second isofocusing system onto input diaphragm of energy analyzer at the same time accelerating or retarding it K₂= 1 to 100 times up to analyzer control energy E_a. Then electrons of analyzed flow passed through energy analyzer are recorded as they arrive at collector. Energy analysis of electrons is made in energy range ΔE of energy difference order in primary beam ΔE_d. EFFECT: enlarged functional capabilities. 2 cl
