Not a lot to go on here except the preamp seems to be on.

What is the value and voltage standoff of the input capacitor?

The tube might be dead if it is surplus. Does it have a pressure indication on the label?
What about a voltage range or figure on the label?

You sort of have to have at least a nice hot piece of U ore!

I hope your scope is a DSO so that you can single shot capture any large cosmics. If not, then you might miss them on an old analog scope in auto roll mode.

Polyethylene is the overall best moderator for the amateur and a, "right on its butt", second would be Paraffin wax which is much easier to obtain, but is a fire hazard in the amounts needed. There is no nearby third choice compared to these two.

You should really strive for the P.E. at a local plastics distributor. Some vendors are happy to sell, at low cost, odd ball cutoff chunks that are no longer of much value. thiese can be stacked and mounded up to make all manner of useful and efficient neutron ovens, caves and howitzers.
