Enum BeamProfile 

pub enum BeamProfile {
    Point,
    Gaussian {
        sigma_m: f64,
    },
    Disc {
        radius_m: f64,
    },
    Rectangle {
        width_y_m: f64,
        width_z_m: f64,
    },
}

Lateral profile of the beam on the front face, about its landing point. Lengths are metres.

Each profile is a plain geometric law (no tabulated data): a Gaussian spot has independent normal y and z offsets with standard deviation sigma_m each (sampled by the Box-Muller transform, two draws); a disc is uniform in area (r = R sqrt(U), azimuth uniform; two draws); a rectangle is uniform in y and z over its full widths (two draws). A point takes no draws.

Variants

Point

Every primary lands exactly at the landing point.

Gaussian

Gaussian spot, standard deviation per axis.

Fields

sigma_m: f64

Standard deviation of each of y and z, m (finite, > 0).

Disc

Uniform disc.

Fields

radius_m: f64

Disc radius, m (finite, > 0).

Rectangle

Uniform rectangle centred on the landing point.

Fields

width_y_m: f64

Full width along y, m (finite, > 0).

width_z_m: f64

Full width along z, m (finite, > 0).
