Intensity jump near alpha_f=5e-7

Run a scattering simulation, e.g. CylindersAndPrism, with modified detector:

def get_simulation(sample):
    beam = ba.Beam(1e9, 0.1*nm, 0.2*deg)
    n = <%= test_mode ? 11 : 100 %>
    detector = ba.SphericalDetector(n, -1e-6*deg, 1e-6*deg, n, 0., 2e-6*deg)
    simulation = ba.ScatteringSimulation(beam, sample, detector)
    return simulation

h

Below about alpha_f=5e-7, the intensity is either very small (e.g. e-36) or zero.
