0002 ParticleFluence set-ups
0003 -----------------------
0004
0005 Sphere
0006 ------
0007 This set-up consists of a full solid target sphere - whose radius and
0008 material can be set via UI commands.
0009 The primary particle is shot from the center of the target sphere
0010 (along the z-axis direction by default).
0011 As scoring volume, we use a thin spherical shell outside the target sphere.
0012 The particle fluences are evaluated in the forward and backward hemispheres
0013 (with respect to the primary particle direction).
0014
0015 ConcentricSpheres
0016 -----------------
0017 Similar to the Sphere one, but with two larger solid target spherical shells
0018 outside the first one, separated by some space filled up by G4_Galactic.
0019 The dimensions of these three targets - which are meant as a simplified
0020 proxy for, respectively, a Tracker (inner sphere), EM (electromagnetic)
0021 calorimeter (middle spherical shell), and HAD (hadronic) calorimeter
0022 (external spherical shell) - and their materials can be set via UI commands.
0023 As scoring volumes, we use three thin spherical shells immediately outside
0024 the inner target sphere and the two target spherical shells.
0025 The particle fluences are evaluated in the forward and backward hemispheres
0026 (with respect to the primary particle direction).
0027
0028 Layer
0029 -----
0030 This set-up consists of a cylinder, with axis along the z-direction, whose
0031 radius, length (i.e. thickness) and material can be set via UI commands.
0032 The primary particle is shot by default along the z-axis, from behind
0033 the target.
0034 As scoring volumes, we use three thin cylindrical layers, filled up by
0035 G4_Galactic, and placed downstream, upstream, and aside of the target
0036 cylinder.
0037
0038 Calo
0039 ----
0040 Similar to the Layer one, the target consists of a simplified cylindrical
0041 hadronic calorimeter, whose properties - size, number of layers, sampling
0042 fraction, active and absorber materials - can be set via UI commands.
0043 Similarly to the Layer case, the the particle fluences are evaluated in the
0044 downstream, upstream and aside positions.
