Title: Measuring FWHM
Post by: Ben Buse on June 08, 2026, 02:08:36 AM
Is it possible to measure the FWHM of different peaks in DTSA-II? Would it be possible to measure the FWHM of the strobe peak?

Thanks

There isn't an automated way to measure the FWHM of peaks in DTSA-II.  The calibration alien will fit spectra to Gaussian peak shapes and modeled backgrounds but it assumes the standard equation for resolution as a function of energy. If the full width of the strobe peak is visible, you can always use the old-school manual method...

Yes on Oxford system when beam isn't on, strobe peak is visible.

I found a julia package to measure the FWHM https://juliapackages.com/p/peaks (https://juliapackages.com/p/peaks)

Or alternatively https://www.effemm2.de/spectragryph/ which opens emsa

@Ben, I do most of my post-processing of .msa files in python where there are many peak=finding routines. In a pinch you can open them with excel, though the TESCAN software messes with the format a bit.
