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...
Are there any ideas why the day time background flux on average is higher than the nighttime flux? These last few days in Colorado have been very clear, and...

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....
