Hi Folks! First off, let me wish you all a Healthy, Happy and Prosperous New Year! I've finally bagged one of Great NorthWest Auction's ENI CDV-700's (the ones...
Hey John, what about commercial UV fluorescent acrylic? I recall that several UV-pumped types are available for decorative stuff. "Air-sea rescue orange" is...
If anyone is interested ...contact me off-list. I have a working PRI 111B scintillator for sale. The unit is complete with DC-DC converter. Runs off of two D...
Hey, Craig, Happy new year to you and yours. Well, now I think it's time to set up a test fixture! Good thought. There's a plastic sign shop here in town that...
Thanks a lot for the correction Geo and John!!! This is actually very good news, since PMT's and scint's are quite expensive and I have to win in the lottery...
Hi folks, I've finally gotten to weeding through old 3-3/4" floppy disks. As an experiment, I measured the resistance of disks from four different sources, and...
Im trying to get on of these NE St-6's working. I have posted pictures of the unit and the connectors in the photos section. I dont know much about these...
Hi all! I did some further thinking on the matter of a one-scintillator muon detector and here are some thoughts (please correct me if there is something...
... There's a plastic sign shop here in town that carries ... they ... Also try the 'clear' wrap found on tamper-evident bottles. Many of these fluoresce in UV...
Hi, David... Well, I spent most of the morning making up an easy-open light tight box with a PMT mounted in the top, looking down at any sample I may want to...
It occured to me that the decay time of the fluorescense might be much longer if the dye is not chosen carefully, so look at the length of the pulse from the...
I thought George once said that hobby store fluorescent plastics don't work for scintilators? Reportedly, the light pulse takes way too long to decay. <pb> -- ...
... You probably know that quinine (aka tonic) water is UV fluorescent. The BIO types use scint fluids (& PMTs) all the time; it would be cool to have one...
That reference was for the ZnS paint, for Alpha detection, useless. Back when I was searching for the best Alpha scintillator screen. I have not experimented...
George, "Wet blankets" are appreciated, too! They cut down on the grumble factor after a failed experiment. :-) So, if you know that the safety seal on my...
Geez. A scientific reason for a drinking party! Room lit up by UV and fluorescing drinks. The next "rave" craze? But seriously, who knows what fluors may spark...
Hi John! ... I did some further research on the specific "berkeley tube" and you're right! The output is still analog and not a digital 0/1 signal as I've ...
... Back in the 80s as an undergrad I heard of a 'twinkie & vaseline' blacklight party at a certain dorm. When I inquired as to "why", I was told that the ...
I can remember my college drinking days (maybe I didn't drink that much) sipping a T&T (Tangeray and Tonic) and observing the glow of the quinine under the...
... Hmmmm. That sounds like a sugar-fueled orgy! :-D ... I can picture the glowing, creme filling- and vaseline-coated bodies writhing on the floor. Yup....
Hi: I'm a newbie at Geiger Counters and have been looking through the files section. The Subject email has links that no longer point to the desired...
Nice tube, but not a direct replacement in the probe housing, too big. You will have to make a housing for it. I make them from PVC plumbing tubing. Details...
Ok, dumb question, but i just bought new batteries for a master 1 radiation dose meter, the little russian kind. I am at a loss as how to put the batteries in!...
The two outer batteries go button side up on the outside edges, and flat side up on the inside (+ side). The cardboard sheet goes towards the inside, with the...
I wish I had read that "primer for new comers sooner"! Good stuff in there. Anyhow, I think I'll pick up a ck1049, and make a new housing. That reasonable...
