Dear forum users,
I have a quite simple question. I have got a flux of protons measured in 1/(cm^2 s sr), I would like to have it in 1/(cm^2 s). Best regards, nykon

Then you should multiple by the number of sr

My answer would be: The area of the sphere with radius of 1m^2 is: [itex]S = 40000 \pi [cm^2][/itex] the effectiv area of the detector is D = 1cm^2, so: [itex]\frac{D}{S} = \frac{1}{40 000 \pi} = \frac{1}{125600} = 7.9 \times 10^{6} [/itex] So the soild angle of my detector should be: [itex]θ_{D} = 4\pi \times 7.9 \times 10^{6}[sr][/itex] So finally: [itex]θ_{D} = 9.92 \times 10^{5} [sr][/itex] Am I right? Best regards, nykon

the protom flux
Yeah, I think that looks great!
