Re: ZnS:Ag phosphor company information

I have been using their EJ400 with a Hamamatsu HC125 for some time now, and have been considering boosing my detector efficiency by changing to liquid. This company will dope a solution of ZnS:Ag with .5% to 1.5% Gadolinium and even encase it for you to your own dimensions in glass or aluminum.

Re: RGA Quandery

<r>Well, Larry, you are, for the most part, correct. Without the matching controller and board, you'd play hell trying to piece a working one together and get it to work properly. Not to mention, some of the older RGA's don't even have RS232 connections. They come with their own displays.<br/> I hav...

Re: I HATE money :)

<t>Tell me about it!!! I dont hate money, but I hate spending so much of it on my fusor. I've so far spent about 25 grand on this thing so far.... since two years before Tom Ligon's article in Analog, and just dropped $5,800.00 more last week on a used maglev turbo and Ion pumps. Ouch!!! Still, thou...

Re: NIF sailing forward.

<t>What makes this technology so neat is that one uses a femtosecond pulsed Nd:YAG or glass laser at less than a joule to start with. Its then dispersed with a blazed diffraction grating or grism - "cleaned" to a single line mode - amplified, then put back in phase with another identical diffraction...

Lets play three questions...

<t>I have three questions regarding this contraption of <br/> mine and hope someone can help...<br/> 1) Can anyone suggest a way to bakeout my SS chamber to achieve a better vacuum? I'm considering Lesker's push-pull linear positioner and stab-in bakeout lamp CF flanged with a tube coupling or somet...

Re: P.I.P.S. Detectors

<t>The Wisconsin team's lead foil is exactly 25 micrometers thick and allows passage of the D3He and D-D protons, but probably lets through too much background noise. Go a step further...consider this...A proton's diameter is 10e-15 m. An X-ray is 10e-11 m. In your quest for a better material, consi...

3 x 10e9 Neutrons / Second in 1992

<r>The following web link describes a neutron producing machine used to remotely detect land mines. It was operational in 1992 and built by the SAIC.<br/> Evidently, it used an ionized deuteron beam to bombard a beryllium target to achieve Li/Be, Be/B, and T/He fusions.<br/> It's not an IEC fusor, b...
