Hi,
do not remove any plastic from the SiPM, it should be epoxy resin and its function is to protect the chip.

Hi Martin, yes, the short distance and the "shape" of the sample could change a lot the final calculation, I did just a try with some simple equipment and simple maths. The ideal would be a software simulation that can take into account the distance between sample and detector and also the...

Hi Martin,
I did some quantitative measurements (at least I tried) :

Hello,
I have a "Krypton" tube too !
Here you can find the spectrum with a small "bump" around 514 KeV

Interesting !

Hi,
if you want I have a spectrum from lanthanum 138 (NaI 63x63mm) from 100g of lanthanum oxide

Hi,
Thallium 208, from thorium, for sure.

Great work !

Hello, you have to run the measure for as long as you can, for example 2 or 3 hours. First take the background for three hours, you memorize it, and after that you take a measure with the sample (as much as you can, 100 g for instance), in the same chart, to have evidence of the difference. Of cours...
