This is interesting. I normally just follow the posts here as I'm mostly into Geiger Counters and Scintillators. I would recommend getting something mildly...
Concerning a safe radiation source for tests, when you order a cloud chamber kit from Edmund Scientific you get a coupon that delivers a bead of lead 210...
Hi Robert, cosmicrays.org and list owner here, Hannes/Captain. Well, about the experiment: 1) As I wrote on the webpage, this is a highly uncertain experiment....
Any opinions from other members so far ? Cari saluti, Capitano. ... http://teachers.web.cern.ch/teachers/archiv/hst2000/teaching/expt/sascha/sascha.htm...
Dear all, i am currently playing arround with an avalanche photo diode (APD). As expected my current setup is quite sensitive to light in the visible range....

Hi Robert You might try taking your Geiger counter to a hardware store and asking to check out the gas lamp mantles. Not so many years ago the mantles were...
You may want to "sacrifice" a regular cheap home-use smoke detector. Many smoke detectors use a small ion chamber as the smoke detecting element. Inside the...
Thanks Noel, I have no problem hacking apart a smoke detector, don't know why I don't just pop down to the store a get a few :-P in the first place, I'll get...
Is there any way to visit the LHC underground areas? Or is it all sealed up and off limits to outsiders? I've been to the Microcosm museum but would like to...
Take your geiger counter to flea markets, yard sales or thrift stores, look for an older alarm clock with a radium dial. My dad's old alarm clock provides a...
for some reason my posts are not delivered (at least to me) so here is a forward ... Subject: Latest from the LHC Date: Fri, 27 Feb 2009 18:02:41 +0100 From:...
Seems fine for me. Clay ... From: particledetector@yahoogroups.com [mailto:particledetector@yahoogroups.com] On Behalf Of Ing. Hannes Mayer Sent: Saturday,...
The answer is yes. I arranged a visit for my college physics group. However we had to cancel due to unforseen circumstances. Educational visits are allowed...
I went out on the weekend and bought a smoke detector for only $7AU which has a nice little alloy disk with americium 241 (according the package). It seems to...
G'day Robert, ... this sounds a little strange to me, since alphas won't go thru the glass of the tube. Most likely your source also produces a good amount of...
That is excellent feedback Hannes, as I was very disappointed that I didn't get the same level reaction in the tube detector as I did with a Geiger counter. As...
