|
Examples in this directory demonstrate specific set-ups in
|
|
which to evaluate particle fluence.
|
|
|
|
\ref ExampleSphere
|
|
|
|
This set-up consists of a full solid target sphere - whose radius and
|
|
material can be set via UI commands.
|
|
The primary particle is shot from the center of the target sphere
|
|
(along the z-axis direction by default).
|
|
As scoring volume, we use a thin spherical shell outside the target sphere.
|
|
The particle fluences are evaluated in the forward and backward hemispheres
|
|
(with respect to the primary particle direction).
|
|
|
|
\ref ExampleConcentricSpheres
|
|
|
|
Similar to the Sphere one, but with two larger solid target spherical shells
|
|
outside the first one, separated by some space filled up by G4_Galactic.
|
|
The dimensions of these three targets - which are meant as a simplified
|
|
proxy for, respectively, a Tracker (inner sphere), EM (electromagnetic)
|
|
calorimeter (middle spherical shell), and HAD (hadronic) calorimeter
|
|
(external spherical shell) - and their materials can be set via UI commands.
|
|
As scoring volumes, we use three thin spherical shells immediately outside
|
|
the inner target sphere and the two target spherical shells.
|
|
The particle fluences are evaluated in the forward and backward hemispheres
|
|
(with respect to the primary particle direction).
|
|
|
|
\ref ExampleLayer
|
|
|
|
This set-up consists of a cylinder, with axis along the z-direction, whose
|
|
radius, length (i.e. thickness) and material can be set via UI commands.
|
|
The primary particle is shot by default along the z-axis, from behind
|
|
the target.
|
|
As scoring volumes, we use three thin cylindrical layers, filled up by
|
|
G4_Galactic, and placed downstream, upstream, and aside of the target
|
|
cylinder.
|
|
|
|
\ref ExampleCalo
|
|
|
|
Similar to the Layer one, the target consists of a simplified cylindrical
|
|
hadronic calorimeter, whose properties - size, number of layers, sampling
|
|
fraction, active and absorber materials - can be set via UI commands.
|
|
Similarly to the Layer case, the the particle fluences are evaluated in the
|
|
downstream, upstream and aside positions.
