Discussion Overview

The discussion revolves around cosmic ray flux rates at various energy levels, specifically focusing on the rates for cosmic rays with energies of 10^{16} eV, 10^{17} eV, 10^{18} eV, 10^{19} eV, 10^{20} eV, and 10^{21} eV. Participants are seeking to understand the arrival rates of cosmic rays at these energy levels, as well as referencing existing literature on the topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant provides known cosmic ray flux rates for 10^{16} eV, 10^{19} eV, and 10^{20} eV, and inquires about the rates for 10^{17} eV, 10^{18} eV, and 10^{21} eV showers.
  • Another participant suggests looking up a review article by Simpson and a book by TK Gaisser for more information on cosmic rays, but does not provide specific flux rates.
  • A request for access to the review article is made by a participant who lacks access to the necessary resources.
  • Another participant responds with information about accessing the journal through a library, cautioning against sharing copyrighted material online.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the flux rates for the requested energy levels, and multiple viewpoints regarding access to literature and resources are presented.

Contextual Notes

Participants express uncertainty about the specific flux rates for 10^{17} eV, 10^{18} eV, and 10^{21} eV showers, indicating a reliance on external literature for further information.

Hi!

I know these cosmic ray flux rates on Earth:
10^{16} eV: the arrival rate is one particle per square meter per year.
10^{19} eV: the arrival rate is one particle per square kilometer per year.
10^{20} eV: the arrival rate is one particle per square kilometer per century.

What are the flux rates of
a) 10^{17} eV showers?
b) 10^{18} eV showers?
a) 10^{21} eV showers?

Thank you!

Hello! Anyone out there?
 
Look up the review article by Simpson entitled "Elemental and Isotopic Composition of Galactic Cosmic Rays" Ann. Rev. Nucl. Part. Sci. 1983, 33 (323-81)

or the book by TK Gaisser "Cosmic Rays and Particle Physics."

I just don't have time to search through them and convert them to the units you are interested in.
 
Ok. Thanks!
 
Can someone send me http://arjournals.annualreviews.org/doi/pdf/10.1146/annurev.ns.33.120183.001543" ? I do not have access, although I use the Jyväskylä University internet connection.

My email address is henri(dot)heinonen(at)mbnet(dot)fi.

Your library has a copy of the journal. (you can find it here:https://jykdok.linneanet.fi/cgi-bin/Pwebrecon.cgi?v1=1&ti=1,1&LANGUAGE=English&Search%5FArg=Annual%20review%20of%20nuclear%20and%20particle%20science&Search%5FCode=JALL&CNT=25&PID=5460&SEQ=20070207003205&SID=1" ) I don't speak whatever language that is (Finnish?) but that is the correct journal as far as I can tell.

Go to library and ask for the correct volume and they will find it for you I am sure. Your library probably doesn't have a electronic subscription.

(Note: In general it is not a good idea to ask people to send you copyrighted material over the internet.)

Yes, that is Finnish.

Ok. Thanks!
