Abstract
Results of upgrading of MAC-1 setup components are described. It is shown that the optimum conditions for detection of low-intensity spectral lines are ensured by the high sensitivity of the instrument to gradations of photoemulsion blackening and by the high resolution of the optoelectronic channel that forms the image of emulsion grains, in combination with the possibility of varying the spectrogram scanning modes, which has been provided by the upgrading. The upgrading of the instrument opens up new avenues for spectroscopy of internal conversion electrons if sufficient statistics is acquired in an experiment. The efficiency of the proposed procedures is demonstrated by the example of extraction of low-intensity K672.35 160Dy and K673.09 160Dy lines in a spectrogram of internal conversion electrons from erbium fractions.
