I wish to call your attention to a nice bibliography on experimental techniques, not all but many ones useful for fusor experimenters:

Experimental Innovations in Surface Science, by John T. Yates Jr.

The title is slightly misleading but the content is invaluable.

Understood!

But keep in mind H2 is very diffusive, so a vented room will assure a non-explosive mixture ratio with air.

Hi Patrick
Thanks for sharing.
Not useful for my project but a friend of mine, in struggle with an electrostatic accelerator will enjoy your info.

But degassing until emptied of gasses, right?
Or do you think that there is a "push-pull" action, loading and outgassing, rytmically?

Hi Jim

Please, comment on your experiences with titanium and degassing.

Agustin Why do you start your long pursuit trying to use a wrong road? Mechanical pump oil has several properties, not only oriented to get a good vacuum but also to protect the steel parts inside the pump. Were are you based? Surely some provider of consumables for vacuum systems, as mass spectrome...
