Multichannel Analyzers of Emission Spectra with Improved Characteristics in the 258–269 nm Region for the Grand Spectrometer

Resumo

A fast multichannel analyzer of emission spectra (MAES) for the Grand spectrometer with a combined hybrid assembly of 12 BLPP-369M1 arrays (for the 190–350 nm spectral range) and one BLPP-2000 array (for the 258–269 nm spectral range) has been created. The minimum exposition time of the analyzer is 3 ms. It is shown that, at the base exposition time of 3 ms, the signal-to-noise ratio for the flashes of the analytical Au 267.595 nm line is a factor of 10 higher when recorded using the BLPP-2000 array as compared to the BLPP-369M1 array.
