I am planning to build a fusor device soon, and am just wondering about whether certain materials would help in the construction of a fusor. I understand that diamond coatings have a very high secondary electron emission figures
(40x ?) at relatively low temperatures. How would this affect electrodes if they were made of say, coated wire?.
Also this particular suggestion is a bit way out there: would platinum or rhodium wire have any catalytic effect (a la cold fusion) on the fusion?
i guess the grids are way out of the multipactor?
reaction area so you'd have to have some metal in the centre.... pure platinum metals have very high melting temperatures so they may survive for a while in that environment, possibly with the wire extending into a cooler are for the heatsinking effect.
Also can i get away with a couple of stacked refrigerator for the vacuum generation?, would that be enough vacuum or should I get something more substantial?.
Finally last but not least can i build something better than the Daimler Chrysler aerospace fusor unit: http://www.dasa.de/dasa/index_e.htm?
/dasa/e/ri/trauen/fusion/spec.htm with 5 x 10^6 neutrons per second.
Thanks in advance
