Hi all, check this: http://www.cosmicrays.org/muon-power-supply.php I got in contact with Charlie Thompson, cloned his circuit, asked for permission to add it...
Hi, I'm new to this group, although, I've been recording cosmic muon data ( at least I think that's what it is) for a couple years now. I'm sending this .pdf...
... Hi Rodney, welcome to the group! Attachments are not distributed via group email to prevent spreading of worms. Please upload the PDF to the group's file...
Rodney, Re: 080312_spike_2hr.JPG The time frame of the spike is quite high. Almost half an hour. If it was just a short spike, I'd say it was a TeV event, but...
Hannes, I wish I knew what the atmospherics were like during that time, but I don't. It seems, though, for folks who are recording these data we should be on...
... Hi Rodney, as I figure from your file names, 080312.... it was the 12th of March 2008, right ? Maybe we can get some weather data from NOAA at this day....
Hi, I recorded an early morning spike (080702_spike.jpg) which I've uploaded to the Rodney_Howe folder. This peaked around 9:30 AM MDT. There were no clouds...
Hello Hannes, I am a member of this group for some time but I have been quiet so far :). I am not an expert in the field but I think I could give you my ...
Alexandra, I don't think I can detect TeV events; at least I'm not using the Pulse Integrated Amplifier detector that way. I'm just monitoring the background...
Hi Rodney, Ok now I have a more clear picture, thanks. Right, I don't think you can be sure that you have seen TeV events with this detector and this...
Thanks Hannes, It looks like I would only need one of those as it has two sensors.. Is that correct? Regards Martyn ... From: particledetector@yahoogroups.com ...
... Yes. And the tubes are much longer than mine which is better (higher counting rate) BTW, my 5kV power supply is finished :-) Will put up a page at CRORG...
Thanks Hannes I have ordered one. Best wishes, Martyn ... From: particledetector@yahoogroups.com [mailto:particledetector@yahoogroups.com] On Behalf Of Hannes...
Alexandra, The detector is on the second floor, and it is not shielded in any way, so I don't know that I'm only seeing muons. I think a detector specifically...
Hi Rodney, yes, I think that's what you need to sort out, what the background noise is and/or design some of shielding, like for example a 10 cm lead...
Hi all, recently I bought a neat PMT http://www.cosmicrays.org/tmp/pmt1.jpg (bought from GEOelectronics http://search.ebay.com/_W0QQsassZgeoelectronics highly...
Hi Hannes, The design of light guides (also called light pipes) is a science in and of itself. You have seen many examples of them in consumer electronics, ...
Alexandra, Thanks' for the reply, I think some kind of lead shielding might be best, perhaps a V shape to shield just the ground: \*/ ( where the * is...
Hi Rodney, I am not sure I got your idea with the V-shape shielding, but I guess that before you try any specific shape try a simple planar shielding above...
Alexandra, I'm experimenting with shielding as you suggested. I also do some radio astronomy, and was fortunate enough to get hold of a MODIS satellite...
Hi Rodney, I don't know if I got your idea exactly. So you have a torus magnet and you place it under the Geiger counter, ok. I have some comments: the...
Rodney, Check your shielding material with a counter before you use it, many materials are slightly radioactive themselves. Almost all rock contains traces of...
... At least not with a GM tube. Using a scintillator, you can measure energy and then check if it's a muon or not. That's when I'm going to try, when I have...
