Hi Fer,
nice spectra!!
Yes my 3x3 is really outstanding in low end energy resolution, especially considering it is a big 3"x3" , something special happened under magical Luuk hand!

Did some experiments with 1g Lutetium and 30g KCl in an attempt to figure out an approximation of the energy/efficiency curve of the detector.

1g of Lutetium turns out quite enough to get a nice spectrum with becqmoni in less than 2 hours...

The approximation is probably rather inaccurate though. Needs more data and it's highly unlikely a simple quadratic curve.
