Most of the necessary part to build back Cell#2 alias EU Cell are here. As Ryan published earlier, I had to change all the internal parts of the cell and restart form clean new. I had to change the tube and the flanges anyway!
Almost the entire new design is glue free. I only need one ceramic glue spot to maintain the assembly together. The use of a reduced thickness mica (1.5mm) will increase the surface of "regeneration" of the active wire in case we need to do it. Because it will less act as a heat sink, conducting thermal energy through the mica.
By the way, this "regeneration" process consist in increasing rapidly the temperature of the wire during a short time under atmospheric condition in order to oxidize the copper that travelled on the surface and make it bubbly. This help to let the hydrogen absorption recover and brake the insulation layer of copper created after intensive heating.
Aside of this, I was pretty disappointed by the quality of the work made by my scientific glassblower that made the preparation of the tube. I wanted to use exactly the same tube as Celani is using. He strongly suggested to do it, because the brand is known to be stronger under pressure and temperature conditions and it thermalises infrareds just right.
As you can see the edges of the tube is too rought to maintain a good pressure/vacuum. The surface must have a better polish.
ETA of Cell#2 is estimated around Tuesday 27th. First Calibrations should be pubished by next Thursday.
