Re: New neutron detector available
I think I will give them a chance and try the components. I'll keep you informed. But it will take some time ..

Re: New neutron detector available
Most important in a report is about at what point in fusion are these things reporting out of any noise or background. Newbies attempting fusion are typically way down in the fusion level. 5,000 - 20,000 neutrons, isotropic.

Re: New neutron detector available
The new device arrived!
Unfortunatly I will not have time to test it within the next weeks.
But working in my head on a test szenario ...
Has anyone else tried to get a hand on the new DOMINO?

Re: New neutron detector available
We look forward to your future reports on the device. Naturally, we would hope for an older neutron detector reading versus the new solid state detector in a single run for comparison. Thanks

Re: New neutron detector available
OK - it took some time - but finally I got some results.
Attached you find the data Philipp and I collected at one of our local research-facility neutron sources.
It seems that the device (within the small red box) is not so much depending on slow neutrons - which is fine!
The source has a very low gamma emission and we hope that the counts we got are almost only from neutrons.
We also did some tests with a Cs-137 source – so we have an idea how sensitive it is to gamma radiation.
We plan to compare it with a brand new detector type (and with a white neutron beam from a nuclear reactor) which is still under development – but this will take a while.
Hope to hear from you - is someone else is going to test it - please come back to me to compare the numbers.
BR,
Werner

your report would make more sense if the axis on your graphs were labeled properly

Re: New neutron detector available
... and here is the moderator now containing the new detector.
It will be filled with paraffin today.

Very nice. Looks like you made the entire thing with a 3d printer?
If your experiment needs statistics, you ought to have done a better experiment.

Re: New neutron detector available
yes, I printed it and filled it with wax.
I can send you the print files (or Inventor files) if you need them.
Attached is a pic of the filling process (with cooling). I used a hose - not the funnel.

Re: New neutron detector available
There is a group buying effort for these detectors at $469..

I did ask you to correct the graphs but after a few months you have not
1./ your data flys in the face of the detector published data
2./ detector sensitvty increases as the neutrons are thermalised your graph shows the opposite??
3./ why a ball for the moderator, the detector is planar so should have been rectangular for best response
