Re: Titanium walls

Ian, John thank you for your comments.
Yes, will require some additional equipment but someone will be able to do.

Titanium walls

Following recent suggestion by Richard to open a discussion about the potential usefulness of titanium as the walls of the fusor chamber, here is some idea. The cost of a full titanium chamber was mentioned as prohibitive. A more economic alternative would be to deposit titanium onto the SS walls. T...

Re: [Requist] Looking for vacuum equipment (NL)

Hi Joep As I stated several times, it is easy to recover a damaged diffusion pump. Try to find some high vacuum seller or mass spectrometer seller and talk with their support people. Some companies discard a damaged diffusion pump, mostly due to two possible problems: cracked glass oil level visor o...

Re: Would a heated Barium oxide filament survive in a deuterium environment?

I see several points to mention: Barium oxide-coated filaments do well in D2 atmosphere. The coating is intended to enhance electron emission. Yttria coating in filaments enhances electron emission and also filament life, being able to be exposed to atmosphere. Barium oxide-coated filaments are able...

Sven
That is almost the situation inside a deuterium discharge lamp, used in spectrometers.

Re: Generate dense, cold plasma?

Hi Sven

This review has many references to different procedures to get cold plasmas.

Re: Paper on neutron counting using ZnS(Ag) phosphors

Hi Richard

Thanks for the comments.
I will rely most in Ag activation and the russian corona tubes.

Re: Paper on neutron counting using ZnS(Ag) phosphors

Hi John Glad to know about your experiment. I will give a try as soon as I get some ZnS:Ag film. My neutron source will be an old vial with Ra paint (from old watch shop) and a small Be window from a damaged X-ray tube, just placing the Be in front of the open vial. The efficiency will be low but I ...

Re: Paper on neutron counting using ZnS(Ag) phosphors

Jon,
It is an interesting paper but nothing is said about neutron fluxes.
The only neutron parameter reported is energy.
Do you think ZnS:Ag may be sensitive enough for the typical fusor production?
