Hi guys, my detector is just a flat CCD (i am trying to determine the cosmic ray background), so based on your replies, the solid angle covered by the CCD, is 2*pi*steradians. Thanks for the replies. Pete.

Hi guys, i have previously posted this question in the 'maths' section but had no reply, so i thought i would try my luck here. I'm having problems understanding the units of a cosmic ray flux graph. The cosmic ray flux is given in 'Counts/cm^2 s str', or the counts per cm squared, per...

Thanks Bob, those calculations make sense. Cheers, Pete.

Thanks again for the info Bob. This is exactly what i need. My last question (honest), what does the 'initial state' np, pn and pp refer to? Sorry if this is a really basic question, but I'm very new to particle physics. I have only dealt with photon interactions with matter before and charged...

Thanks for the reply Bob, this is exactly what i was looking for. The only issue is, i need the cross sections up to 1E13 eV. The maximum energy seems to be fixed at ~ 1E8 eV on the plot. I didn't see any options, but is there any way of increasing the limits? If not, do you have any idea how...

Hi guys, I am trying to calculate the macroscopic cross section (scattering and absorption) for high energy neutrons between 1 MeV and 10^7 MeV in Silicon. I am using the macroscopic cross section to determine the mean free path. To calculate the macroscopic cross section, i need to know the...

Hello all, i am using the Beth-Bloch equation to determine the energy deposited by charged particles in matter (namely protons, pions and muons). In the formula, is the number for incident particle charge in relative charge units (i.e. -1 for electron and +1 for a proton), as...
