Re: Hi from Pieter at Linnaeus University

@Steven: Ah, a piece of high-Z material between the detectors. That will be a nice teaching idea. And then students can try to find out the cause.

@Karl: I am a lecturer here in Växjö. My research background is in x-ray spectroscopy of solids, often using synchrotrons.

Re: Hi from Pieter at Linnaeus University

Hi Steven, I did a coincidence measurement with a Na-22 source, using PRA and two simple passive low-pass detectors. The result was very clear, all the background disappears, and it should be even better withe the GS drivers that I ordered. We also have a plastic scintillator, with which I intend to...

Hi from Pieter at Linnaeus University

I am very impressed by all the enthusiasts here. I also like playing with nuclear stuff, but in my case my employer is paying for my hobby: I am taking care of the course lab at the university. We had a bunch of NaI(Tl) scintillation detectors, lots of lead, a small neutron source with 3 mCi radium,...

Re: Tritium spectrum

Why could not this be Bremsstrahlung? The beta particle has energies up to 18.6 keV. The low-energy x-rays get absorbed by the air, the glass, the window.

The periodic-table interface is really useful: http://www4vip.inl.gov/gammaray/catalogs/catalogs.shtml

Software Defined Radio instead of sound card?

I just got myself a HackRF radio, working on getting it to work. My plan was to try to use it for magnetic resonance spectroscopy. But now the thought occurred to me: could one use such a thing for getting the fast pulses from the PMT? Because it is a pity to put them through low-pass filters so tha...
