## Summary:

- Energy resolution of a homogeneous calorimeter

## Main Question or Discussion Point

Hi

I want to look at the energy resolution of a homogeneous calorimeter, in the literature I found that is given by

σ/E = a ⊕ b/√E ⊕ c/E and I found that the ⊕ means quadratic sum, what does quadratic sum mean?

Thanks

Aaron
