Re: Update on good ole Carl Willis

Yes, Carl impressed me as much as anyone I have ever met. His exuberant, measured demeanor has a winning way about him. His willingness to help all who will listen is one of his best traits.

Re: Deuterium lecture bottles on ebay

As you note this is common across the board in elemental analysis once you cross over into the 99% or high purity range. Super human effort, at super human cost to the buyer is always found in such rigid demands for purity. After such costs, especially in the metals biz is "form"! Wire and foils are...

Re: Pulse x-ray generators from ebay

Anyone willing to go through the hassle of moving and saving data and doing the work needed, deserves every consideration. I am the garbage man, the destroyer of wrongful things placed here and, sadly, even valuable data put in the wrong location where long held and often repeated warnings are clear...

Re: Vacuum Chamber Construction

Re: Fusor theory variant on arxiv.. EV Tsiper

I hope if you do play with a turbo pump, it survives longer than mine did in my recent fusor effort. It amazes me how they can be both wonderful and evil at the same time. Of course we do play rough with them.

Re: Fusor theory variant on arxiv.. EV Tsiper

Re: 150kVp 50ns pulsed x-ray sources on ebay

As always, these are not detailed discussion forums.
