A. Kinomura et al., MICRO-RBS ANALYSIS USING A TOROIDAL ELECTROSTATIC ANALYZER, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 77(1-4), 1993, pp. 140-143
A toroidal electrostatic analyzer was Installed in a microbeam line fo
r local backscattering analysis with high energy resolution and simult
aneous detection of angular ion distributions. The secondary electron
image of gold patterns on silicon could be obtained with a minimum spo
t size of 8 x 8 mum2. The energy resolution of the toroidal analyzer s
lightly decreased with the decrease in the spot size. Changes in probe
position gave rise to energy shifts of leading edges in RBS spectra.
