Hi Paradigmnoia , whilst I agree there is a lot to be understood in that spectrum. I think the peak you chose in that plot for the comparison is at a wave length some way bellow the one used for his calculation which was at 357 nm I think? If I’m correct that peak corresponds to the much smaller broader feature to the right.
It’s much more likely the peaks you noted are from emmision lines from the surface of the plasma or surrounding gas in the line of sight I think . Clearly it’s not from an optically thick region. I’m curious what they tell us though.
I guess we also need to take in to account the absorption of the containing material.
I’m very curious what you and Can come up with with that spectrum. There is a lot of structure there and it seems pretty dynamic.
Are there any indicators of specific spectra lines such as for Helium 3 or 4, Lithium etc?.
What could explain the two broader features that seem to Apear? Would this be two separate regions experiencing different scattering? Or is there absorption from the casing playing a role?
Is it comparable to spectra from other plasma lamp assemblies etc?
