... like a regular PMT, but there are actually 2 PMTs inside. ... I'd ... sufficient ... Hannes, We're thinking on the same lines, I believe. All air would do...
Hi Jeff, ... Yep, thinking on the same lines! :-) Well, on the other hand, meanwhile, I have not that big problem with false detections, since with that small ...
Hannes, You picked up on something I completely overlooked. Muon transit time. My tubes are less than a meter apart. Back to checking and testing my set...
I have two spare "GeoProbes" with HVPS, preamps and pulse shapers. If I made a coincidence detector would this setup be an effective muon counter? What would...
... Hi Jeff, designer of the mu-det here speaking :-) Yeah that is a problem I sometimes stumble upon too, when building stuff with e.g. Japan-Transistor or ...
Hi Hannes Farnell UK no longer stock the TIC106N, but suggest this as an alternative: http://uk.farnell.com/9104291/semiconductors-discretes/product.us0?sku=v ...
... Hi Martyn, from the specs it looks almost the same as the TIC106N but more current, but that is not an issue here. No guarantee from my side, but I see no...
http://www.cosmicrays.org/tmp/mdt.jpg is that a muon det. or *IS* that a muon det. :-) And that is just one of the XXXXX panels of the ATLAS/LHC Cheers, Hannes...
... Hmmm... looks like a supercold muon storage tank. The tubes will be filled with muon, right? :-D They seem heavy muons, too. Look at the hook on the left. ...
... Ehi, ciao Marco! Che sorpresa! Come va ? Yes, you're right. It is actually used (top secret information from one of my time traveling agents, who just came...
I am not involved in building particle detectors, but I mention that in secondary school chemistry classes I show the students a geiger counter; most schools...
Perhaps folks have answers to a question: I've been reading a very well researched book, I think, by Michael W. Friedlander, 'A Thin Cosmic Rain', Harvard...
Hi R I have read your question a number of times, but I must admit that I have no idea what you are talking about. Please consider rewriting it in standard ...
John, I think you've answered my question, just in the fact that it is very likely a dumb question. However, I don't understand where all these muons are...
... Hannes, I can get SCRs at trigger voltage 1.3V. Is that close enough? The GMTs I have are meant to work at 900V, so that really limits the V_DRM I can...
Hi R, I don't think your question in dumb because you want to know more about the background, but I think you should explain what you understand as background....
Alexandra, Thanks' for the references, I've ordered the Astroparticle book by Grupen, the other one by Gierder is really expensive ($232), I'll wait on that...
hello I have been reading these strands, much as Johnhas, and also I am unaware of the topic. Symmetry breaking would be difficult to detect unless you had...
Thank you for this nice report, Hannes. The edge of space is generally taken to be 100 km or 62 miles. where the atmosphere is completely ionized. In 1964...
hannes, how much energy did you detect?? i would love to know! the less shielded from the atmosphere that you are the more energy that should be created! i was...
i bought this defense geiger counter off of ebay because i wanted to see cosmic rays first hand in the natural background radiation and also make sure im safe...
guys actually dont worry about responding, im just going to send it back. i dont like seeing the geiger counter not read correctly. it was neat seeing it...

If it responding to the check source why do you think it is not reading correctly? A near contact reading of the check source should be about mid-scale on the...
Alexandra, Thank you for the reference of Claus Grupen, 'Astroparticle Physics', Springer, 2005. I am learning a lot from this book. However I still have...
