Input Assumptions
38MeV ebeam
150mA beam current
30μm ebeam focus (miniβ)
1ps micropulse
4μs macropulse
3μm laser wavelength
30μm laser focus
5MW peak laser power
I calculate a total of 291 x-rays per micropulse scattered into 2π in
the electron rest frame.
In the lab frame this folds into a 1/γ cone with a peak on axis energy
of 9.1keV.
The total macropulse yield is 3.3e6 photons.
