Sažetak
We have investigated channeltron operating in coincidence with silicon surface barrier detector for detection of extreme low energy particles. By use of Po-209 radionuclide and silver backing, a radiactive source was prepared as a fine emitter of released alpha particles, conversion electrons, recoil Pb-205 ions and knock out silver ions. To avoid parasite coincidence events mainly from channeltron anode RC circuit, we have applied appropriate Faraday screens. After getting proper counting rates, composite spectra were recorded. Based on time-of-flight and secondary electron emission coefficient arguments, particular spectra of mentioned particles were extracted. Final experimental data analysis enabled us to found channeltron efficiency curves for electrons, lead ions and silver ions with low detection thresholds at 40 eV, 4 keV and 1.7 keV, respectively.
