ITER - Just th' facts m'am.

All who think real power fusion will be done or even claimed by ITER might want to read this. pushed out to 2035 now with no net power expected as a good result!? http://news.newenergytimes.net/iter-fusion-power-output-consumption-facts-and-falsehoods/ Billions going down an ever deepening rat hole ...

The History of D-T fusion at ITT

In rolling through my past notes and interviews I found the answer to the foggy issue of when D-T fusion began at the ITT - Farnsworth effort. The URL below goes way back to my digging into the issue via early phone interviews in 1998 where no one really remembered definitively as to be read below. ...

Re: Digital X-ray dosimeters on ebay 15keV+ sensitivity

Alas, so many manufacturers rely on such docking stations to set up custom ranges of their dosimeters. Modern electronics in these systems make them so versatile, but also most difficult in some instances to use if purchased surplus. I have a number of capacitive dosimeters of the pen type by victor...

Re: Fusor Running, No Neutron Detection

Your background count sounds about right. Sadly, that is only encouraging. Too bad you don't have access to a warranted neutron source. A good scintillator will always count far more counts from any U mineral source than a GM counter as gammas will be counted from the guts of the mineral, while the ...

Re: Fusor Running, No Neutron Detection

The problem is either the gas or the counter. It is reasonable to suspect the counter if it has never counted in a known neutron field. I have been loath to respond as I have no experience with cross fusors, yet. Neutron counters are another matter. What is your detector tube? What is its size" What...

My Biographical Sketch I was an amateur scientist all my live and still am. I was interested in electronics, chemistry, radiation and amateur rocketry in the 50's and 60's. Received my first GM counter at age 10. I tended towards physics as I grew older, but got my degree in electronics just in tim...

Re: Precipitator Failure

Sorry about the rebound into your 12 volt supply. I am leary of most any switcher by the chi-coms. High voltage ones are no real gems, as a rule. Switchers are all about a snap-on of the drive voltage. Variacs are not on the most favored list for start up. These supplies work off of inrush current t...

Re: The "Waterstar Summit" - January, 2020

Thanks for the images. I think the Meiro grid was independently discovered at fusor.net. It is a natural grid for those looking for solutions to avoid the nightmare of trying to assemble the classic geodesic. It is impossible to call it the farnsworth grid as there were many, many of them. Of course...

Re: The "Waterstar Summit" - January, 2020

Simple observation shows the Bain image is an octahedron and Pem is wearing a miniature 6 holed device, probably machined from a miniature cube of metal. Not the same at all. Bain's image is, therefore, a real inner grid from the model shop and might be the same as that in the original seen in the C...
