We wanted to look at the noise background of the spectrometer, to check that our signals would be above background. We take 3 10s spectra covering the input to the spectrometer.
Spectra 1:
Spectra 2:
Spectra 3:
We then subtract each pair from each other to look at the residual noise background. The background appears to be order 10-15 counts for most of the spectrum.
