Hi all! Just came back from my vacation in Italy: 1st week: European Cosmic Ray Symposium in Florence 2nd week: Toscana and Liguria It was fantastic - met many...
[CC to the particledetector group] Hi Lloyd! Welcome aboard :-) ... Pretty cool! Could you describe your system a bit more ? Which tubes ? Coincidence circuit...
Hannes That was a very interesting link to strangelets that you put on this page. I went to the FAQ's, hoping that somebody had explored the obvious question ...

... Hi John! I did not have time to read the whole strangelet-poster at the ECRS, but I will do as soon as I get it via email. Maybe it covers that. The...
... Hi Lloyd! Welcome aboard! :-) ... I also thought about this type, but the price is a bit high. If I may ask, where did you buy it and what did it cost ? ...
I forget off hand just where I bought it, I will have look to see where I got it from. But I recall the unit cost me some $600.00 but the was the counter and...
I got mine from, I just looked from www.seintl.com I bought the Inspector EXP. When I bought this, it was not for just seeing what is coming in, in the form of...
Now here is a mind bender question for you. A GM tube will pick up and show a hit from Alpha particals and show hits from X-Ray and Gamma Rays, but here is the...
... Hi Robert! I've asked one particle physicist at the ECRS about this and he said that it should be possible when the detector is not in the Geiger region...
... Hi Lloyd, I don't think that is possible. In order to detect only xrays you need a specific xray detector, which only detects xrays. It's not that easy to...
Hi Guys My understanding is that gamma and x-rays are identical in as much as they are both electromagnetic waves, and there is an overlap in frequency range. ...
What I have done is this. I have placed a 1/4 lead plate in front of the GM pan-cake to block X-rays. This has worked as a have a X-ray emitter and I do not ...
I am no expert by a long shot...BUT! This is what I know of the two. X-rays are a lower power and can be blocked with even as little as 1/16 of a inch of lead....
... Hi Lloyd! Indeed! The energy (frequency) is the difference. ... That would be most muons and all other sort of high energetic particles. Speaking of other...
The danger of a Alpha emitter is that when it comes to power it is rated as high " Q " like that of 10 or so. While say U-237 is not all that bad. Gamma, I ...
I recall this from when I was a kid from old hospital stuff. There was some type of screen that when X-rays would hit it, it would give off a glow. What was...
... That would be most muons and all other sort of high energetic particles. Speaking of other particles: Anyone owns a deep cave ? Ever thought of a Neutrino...
Hi: Some time ago I read all the info on the Berkeley Lab web page http://www.lbl.gov/abc/cosmic/ This unit uses two photo multiplier tubes that see the light...
Hi Brooke! ... The inverters with the 1nF and 22k do some pulse shaping which then are fed to the LM555 monoflops. As long as the 2 pulses from the 2 detectors...
... Wow, $400 for the detector electronics! I really should go into business. ;) Joseph -- Joseph A. DiVerdi, Ph.D., M.B.A. http://xtrsystems.com/...

Hi Hannes, Yes as a matter of fact! Here it is: Ned Hi Ned, Well, here's what Muzaffer said. I think he only has the vaguest idea what is in those chambers....
Hi: I've been looking into different muon sensor projects and have some info. Berkeley ... This sensor was designed for use in high schools and they have ...

Hi Brooke! ... [snip] ... 800 would be a reasonable price, but I inquired at electrontubes some time ago and they told me one(!) original tubes of the Berkeley...
