I tried now again and it's better. Probably some issue with your web hosting. I assume it's some shared hosting and that is often very unreliable and depends on load of others on the same node.
For me sometimes also the forum takes about a minute to load.. Happens for the last couple of weeks.

Hi Steven, I wanted to download the file but recently access to your site and forum from my location (Central Europe) is terribly slow. My download speed for that file is 8 KB/s which is something I've seen in the 90s.. So it looks like I won't be able to download it...

Hi Marco, on the contrary, I'm rather impressed by your device as it delivers very good results given it's a larger crystal and CsI.. Also your peaks are pretty well calibrated, not far off. Yes, I believe the "H" and "I" peaks are coming from Pa234m: http://nucleardata.nuclear.l...

Here my spectrum made using the CapeSym SrI2(Eu) with temperature compensation.
I calibrated this with Cs137 for its 32 keV peak too, it's quite sensitive at lower energies, so it should be accurate. It's showing a similar peak @ 34 keV.
The reference picture above says it's escape peaks.

"D" might also be the U X-Ray
For reference:

Thorium metal:

Co60, very nice resolution:

Sorry, I don't have any X-Ray technology.
Just finished the energy correction/calibration. Was struggling with that as it didn't work until I figured out that the channel/energy entries in the table need to be in ascending order.
